NCP5393 2/3/4-Phase Controller for CPU Applications
The NCP5393 controls up to four VDD phases and one VDDNB phase to provide a buck regulator solution for current and next-generation AMD processors. The NCP5393 incorporates differential voltage sensing, differential phase current sensing, optional load-line voltage positioning, and programmable VDD and VDDNB offsets to provide accurately regulated power parallel- and serial-VID AMD processors. Dual-edge multiphase modulation provides the fastest initial response to dynamic load events. This reduces system cost by requiring less bulk and ceramic output capacitance to meet transient regulation specifications. High performance operational error amplifiers are provided to simplify compensation of the VDD and VDDNB regulators. Dynamic Reference Injection further simplifies loop compensation by eliminating the need to compromise between response to load transients and response to VID code changes.

Functional Description
General
NCP5393 is an universal CPU Power Supply Controller compatible with both Parallel (PVI) and Serial (SVI) protocols for AMD Processors. The device provides complete control logic and protections for a high-performance step-down DC-DC voltage regulator, optimized for advanced microprocessor power supply supporting both PVI and SVI communication. It embeds two independent controllers for CPU CORE and the integrated NB, each one with its set of protections. The Controller performs a single-phase control for the NB Section and a programmable 2- to-4 phase control for the CORE Section featuring Dual-Edge multiphase architecture. NCP5393 also supports V_FIX mode for board debug: in this particular configuration the SVI bus is used as a static bus configuring 4 operative voltages for both the sections and ignoring any serial-VID command. It can be used for the board debug before plugging-in the CPU. The NCP5393 incorporates differential voltage sensing, differential phase current sensing, optional load-line voltage positioning, and programmable VDD and VDDNB offsets to provide accurately regulated power parallel- and serial-VID AMD processors. Dual-edge multiphase modulation provides the fastest initial response to dynamic load events. NCP5393 is able to detect which kind of CPU is connected in order to configure itself to work as a Single-Plane PVI controller or Dual-Plane SVI controller. The NCP5393 manages On the Fly VID transitions and maintains the slew rates as defined when the transitions take place. NCP5393 is available in TQFN48 Package.
Remote Output Sensing Amplifier (RSA)
and the Vcore ground reference point to VSN. This configuration keeps ground potential differences between the local controller ground and the Vcore ground reference point from affecting regulation of Vcore between Vcore and Vcore ground reference points. The RSA also subtracts the DAC (minus VID offset) voltage, thereby producing an unamplified output error voltage at the DIFFOUT pin. This output also has a 1.3 V bias voltage as the floating ground to allow both positive and negative error voltages.
Precision Programmable DAC
A precision programmable DAC is provided and system trimmed. This DAC has 0.5% accuracy over the entire operating temperature range of the part. The DAC can be programmed to support both PVI and SVI VID code specifications.
High Performance Voltage Error Amplifier
The error amplifier is designed to provide high slew rate and bandwidth. Although not required when operating as the controller of a voltage regulator, a capacitor from COMP to VFB is required for stable unity gain test configurations.
Gate Driver Outputs and 2/3/4 Phase Operation
A true differential amplifier allows the NCP5393 to measure Vcore voltage feedback with respect to the Vcore ground reference point by connecting the Vcore reference point to VSP,
The part can be configured to run in 2-, 3-, or 4-phase mode. In 2-phase mode, phases 1 and 3 should be used to drive the external gate drivers, G2 and G4 must be grounded. In 3-phase mode, gate output G4 must be grounded. In 4-phase mode all 4 gate outputs are used as shown in the 4-phase Applications Schematic. The Current Sense inputs of unused channels should be connected to GND. Please refer to table "PIN CONNECTIONS vs. PHASE COUNTS" for details.

Differential Current Sense Amplifiers and Summing Amplifier
Four differential amplifiers are provided to sense the output current of each phase. The inputs of each current sense amplifier must be connected across the current sensing element of the phase controlled by the corresponding gate output (G1, G2, G3, or G4). If a phase is unused, the differential inputs to that phase's current sense amplifier must be shorted together and connected to the GND. The current signals sensed from inductor DCR are fed into a summing amplifier to have a summed-up output. The outputs of current sense amplifiers control three functions. First, the summing current signal of all phases will go through DROOP amplifier and join the voltage feedback loop for output voltage positioning. Second, the output signal from DROOP amplifier also goes to ILIM amplifier to monitor the output current limit. Finally, the individual phase current contributes to the current balance of all phases by offsetting their ramp signals of PWM comparators.
Oscillator and Triangle Wave Generator
oscillator generates up to 4 symmetrical triangle waveforms with amplitude between 1.3_V and 2.3_V. The triangle waves have a phase delay between them such that for 2-, 3and 4-phase operation the PWM outputs are separated by 180, 120, and 90 angular degrees, respectively. When the NB phase is enabled, in order to ensure that the VDDNB oscillator does not accidentally lock to the VDD oscillator, the VDDNB oscillator will free-run at a frequency which is nominally 1.25 ratio of fVDD.
CPU Support
NCP5393 is able to detect the CPU it is going to supply and configure itself accordingly. At system Start-up, on the rising-edge of the EN signal, the device monitors the status of VID1 and switches in PVI mode (VID1 = 1) or SVI mode (VID1 = 0). When in PVI mode, NCP5393 uses the information available on the VID[0:5] bus to address the CORE Section output voltage. NB Section is kept in HiZ mode. When in SVI mode, NCP5393 discards the information available on VID0, VID4 and VID5 and uses VID2 and VID3 for SVC and SVD respectively.
PVI - Parallel Interface
The controller embeds a programmable precision dual-Oscillator: one section is used for the CORE and it is a multiphase programmable oscillator managing equal phase-shift among all phases and the other section is used for the NB section. The oscillator's frequency is programmed by the resistance connected from the ROSC pin to ground. The user will usually form this resistance from two resistors in order to create a voltage divider that uses the ROSC output voltage as the reference for creating the current limit setpoint voltage. The oscillator frequency range is 100_kHz per phase to 1.0_MHz per phase. The
PVI is a 6-bit-wide parallel interface used to address the CORE Section reference. According to the selected code, the device sets the CORE Section reference and regulates its output voltage. NB Section is kept in HiZ; no activity is performed on this section. furthermore, PWROK information is ignored as well since the signal is propietary of the SVI protocol. Start-up sequences before soft start and after soft start are given in Figure 9. Voltage identifications for the 6Bit AMD mode is given in Table 1.

SVI - Serial Interface SVI is a two wire, Clock and Data, bus that connects a single master (AMD processor) to one NCP5393. The master initiates and terminates SVI transactions and drives the clock, SVC, and the data SVD, during a transaction. The slave receives the SVI transactions and acts accordingly. SVI wire protocol is based on fast-mode I2C. The SVI communications are given in Figure 10. SVI interface also considers EN and PWROK signals for start-up. The device returns a PWRGOOD signal if the output voltages are in regulation. The VID codes for SVI are given in Table 2. The start-up sequences before and after soft start are given in Figure 11.

Hardware Jumper Override - V_FIX
VFIX is an active low pin and when it is pulled low, the controller enters V_FIX mode.The voltage regulator can be powered when an external SVI bus master is not present. When in VFIX mode, all of the voltage regulator's output voltages will be governed by the information shown in Table 3, regardless of the state of PWROK. VFIX mode is for debug and bring-up only. If VFIX mode is necessary for processor bring-up, VFIXEN, SVC, and SVD should be connected with jumpers to either ground or VDDIO through suitable pull-up resistors. SVC and SVD are considered as static VID and the output voltage will change according to their status.

* This capture is INDEPENDENT of any other signal.
SVI/PVI is determined by sampling VID[1] during rising edge of ENABLE (SVI: VID[1]=0, PVI: VID[1]=1). Once SVI/PVI is determined, the VID controller is enabled and increments to the Boot VID at the Soft Start rate. VFIXEN mode is entered once VFIXEN is asserted. If VFIXEN is asserted prior to the VID controller reaching the Boot VID, the VID controller will move to the VFIXEN VID. Once the first VID value is reached (either BOOT VID or VFIXEN VID), the VID will now increment at the Normal rate. Once the VID controller is enabled, the VID controller can receive VFIXEN VIDs, independent of PWROK which is ignored in VFIXEN mode. If VFIXEN is de-asserted, the device PORs. This occurs independent of ENABLE
*

PWROK De-assertion
*
Start-up sequences are presented below: Boot VID is captured from SVC and SVD pins on rising edge of ENABLE.
Anytime PWROK de-asserts while EN is asserted, the controller uses the previously stored BOOT VID and regulates all planes to that level performing an on-the-Fly transition to that level. PWRGOOD remains asserted in this process.

Protection Features:
Undervoltage Lockout
An undervoltage lockout (UVLO) senses the VCC and VCCP input. During powerup, the input voltage to the controller is monitored, and the PWM outputs and the soft-start circuit are disabled until the input voltage exceeds the threshold voltage of the UVLO comparator. The UVLO comparator incorporates hysteresis to avoid chattering, since VCC is likely to decrease as soon as the converter initiates soft-start.
Overcurrent Shutdown
A programmable overcurrent function is incorporated within the IC. A comparator and latch make up this function. The inverting input of the comparator is connected to the ILIM pin. The voltage at this pin sets the maximum output current the converter can produce. The ROSC pin provides a convenient and accurate reference voltage from which a resistor divider can create the overcurrent setpoint voltage. Although not actually disabled, tying the ILIM pin directly to the ROSC pin sets the limit above useful levels effectively disabling overcurrent shutdown. The comparator noninverting input is the summed current information from the VDRP minus offset voltage. The overcurrent latch is set when the current information exceeds the voltage at the ILIM pin. The outputs are pulled low, and the soft-start is pulled low. The outputs will remain disabled until the VCC voltage is removed and re-applied, or the ENABLE input is brought low and then high.
Output Overvoltage and Undervoltage Protection and Power Good Monitor
voltage, the PWRGOOD goes low, the DRVON signal remains high, the PWM outputs are set low. The outputs will remain disabled until the VCC voltage is removed and reapplied. Every time the OV is triggered it will increment the OV counter. If the counter reaches a count of 16 then the OV condition will latch into a permanent OV state. It will require POR or disable/enable to restart. Prior to latching if the OV condition goes away then normal operation will resume. An OV decrement counter is also incorporated. It consists of a free-running clock which runs at 8x the PWM frequency. So essentially every 4096 PWM cycles the OV counter will decrement. For example, for a max PWM frequency of 1 MHz, the counter decrements roughly every 4 ms and for a PWM frequency of 400 kHz, it would be about every 10 ms. During normal operation, if the output voltage falls more than 350_mV below the DAC setting, the PWRGOOD pin will be set low until the output voltage rises.
Soft-Start
The NCP5393 simply ramps Vcore to boot voltage at a fixed rate of 2 ms (0.8 mV/uS), and then reads the VID pins to determine the DAC setting. Then ramps Vcore to the final DAC setting at the Dynamic VID slew rate of up to 3.25 mV/mS. In SVI mode, SoftStart Time is intended as the time required by the device to set the output voltages to the Pre-PWROK Metal VID. In PVI mode, VID[0:5] or V_FIX VID in V_FIX mode are the set output voltages. Typical soft start sequence timing in SVI mode is given in Figure 12.
An output voltage monitor is incorporated. During normal operation, if the output voltage is 250 mV over the DAC

Programming the Current Limit and the Oscillator Frequency The demo board is set for an operating frequency of approximately 330 kHz. The ROSC pin provides a 2.0 V reference voltage which is divided down with a resistor divider and fed into the current limit pin ILIM. Calculate the total series resistance to set the frequency and then calculate the individual RLIM1 and RLIM2 values for the divider. The series resistors RLIM1 and RLIM2 sink current from the ILIM pin to ground. This current is internally mirrored into a capacitor to create an oscillator. The period is proportional to the resistance and frequency is inversely proportional to the total resistance. The total resistance may be estimated by Equation 2. This equation is valid for the individual phase frequency in both three and four phase mode.

The inductors on the demo board have a DCR at 25C of 0.75 mW. Selecting the closest available values of 16.9 kW for RLIM1 and 13.7 kW for RLIM2 yield a nominal operating frequency of 330 kHz and an approximate current
limit of 152 A at 100C. The total sensed current can be observed as a scaled voltage at the VDRP pin added to a positive, no-load offset of approximately 1.3 V.

OUTPUT OFFSET VOLTAGES
External offset voltages from 0 mv to 800 mV above the DAC' can be added for the VDD and VDD_NB independently. Offset is set by a resistor divider from VCC to GND. Output offsets are ratiometric to VCC. As VCC changes, the on-chip scaling factors change by the same amount: Offset = 0.8 V x VOFFSET/VCC For example: For 0 V offset: pin voltage = GND; For 800 mV offset: pin voltage = VCC

The input to the OFFSET pin for the VDD output is encoded by an internal ADC. The input to the NB_OFFSET pin for the VDDNB output is encoded by the same ADC. The reference for this ADC is VCC. The ADC's output is ratiometric to VCC. Voffset IN represents the voltage applied to the OFFSET or NB_OFFSET pin. It is intended that these voltages be derived by a resistive divider from Vcc. The recommended total driving impedance is <10 kilohms.
