NCP9001
OPERATION DESCRIPTION
Overview
The NCP9001 uses a constant frequency, current mode step-down architecture. Both the main (P-Channel MOSFET) and synchronous (N-Channel MOSFET) switches are internal. It delivers a constant voltage from either a single Li-Ion or three cell NiMH/NiCd battery to portable devices such as cell phones and PDA. The output voltage is set by the external resistor divider. The NCP9001 sources at least 600 mA, depending on external components chosen. The NCP9001 works with two modes of operation; PWM/PFM depending on the current required. The device operates in PWM mode at load currents of approximately 40 mA or higher, having voltage tolerance of "3% with 90% efficiency or better. Lighter load currents cause the device to automatically switch into PFM mode for reduced current consumption (IQ = 30 mA typ) and extended battery life. Additional features include soft-start, undervoltage protection, current overload protection, and thermal shutdown protection. As shown in Figure 1, only six external components are required for implementation. The part uses an internal reference voltage of 0.6 V. It is recommended to keep the part in shutdown until the input voltage is 2.7 V or higher.
PWM Operating Mode
125 ns/div
Figure 23. PWM Switching Waveform (Vin = 3.6 V, Vout = 1.8 V, Iout = 300 mA) PFM Operating Mode
In this mode, the output voltage of the NCP9001 is regulated by modulating the on-time pulse width of the main switch Q1 at a fixed frequency of 1.5 MHz. The switching of the PMOS Q1 is controlled by a flip-flop driven by the internal oscillator and a comparator that compares the error signal from an error amplifier with the sum of the sensed current signal and compensation ramp. At the beginning of each cycle, the main switch Q1 is turned ON by the rising edge of the internal oscillator clock. The inductor current ramps up until the sum of the current sense signal and compensation ramp becomes higher than the error voltage amplifier. Once this has occurred, the PWM comparator resets the flip-flop, Q1 is turned OFF and the synchronous switch Q2 is turned ON. Q2 replaces the external Schottky diode to reduce the conduction loss and improve the efficiency. To avoid overall power loss, a certain amount of dead time is introduced to ensure Q1 is completely turned OFF before Q2 is being turned ON.
Under light load conditions (<40 mA), the NCP9001 enters in low current PFM mode operation to reduce power consumption. The output regulation is implemented by pulse frequency modulation. If the output voltage drops below the threshold of PFM comparator (typically Vnom-2%), a new cycle will be initiated by the PFM comparator to turn on the switch Q1. Q1 remains ON until the peak inductor current reaches 200 mA (nom). Then ILIM comparator goes high to switch off Q1. After a short dead time delay, switch rectifier Q2 is turned ON. The negative current detector (NCD) will detect when the inductor current drops below zero and sends the signal to turn off Q2. The output voltage continues to decrease through discharging the output capacitor. When the output voltage falls below the threshold of the PFM comparator, a new cycle starts immediately.

Cycle-by-Cycle Current Limitation
From the block diagram (Figure 3), an ILIM comparator is used to realize cycle-by-cycle current limit protection. The comparator compares the LX pin voltage with the reference voltage, which is biased by a constant current. If the inductor current reaches the limit, the ILIM comparator detects the LX voltage falling below the reference voltage and releases the signal to turn off the switch Q1. The cycle-by-cycle current limit is set at 1200 mA (nom).
Short Circuit Protection
consumption will be 0.3 mA (typical value). Applying a voltage above 1.2 V to EN pin will enable the device for normal operation. The typical threshold is around 0.7 V. The device will go through soft-start to normal operation, however, the EN pin should be tied low while the input voltage on VIN pin is rising up.
Thermal Shutdown
When the output is shorted to ground, the device limits the inductor current. The duty-cycle is minimum and the consumption on the input line is 300 mA (Typ). When the short circuit condition is removed, the device returns to the normal mode of operation.
Soft-Start
The NCP9001 uses soft-start (300 ms Typ) to limit the inrush current when the device is initially enabled. Soft-start is implemented by gradually increasing the reference voltage until it reaches the full reference voltage. During startup, a pulsed current source charges the internal soft-start capacitor to provide gradually increasing reference voltage. When the voltage across the capacitor ramps up to the nominal reference voltage, the pulsed current source will be switched off and the reference voltage will switch to the regular reference voltage.
Shutdown Mode
Internal Thermal Shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction temperature is exceeded. If the junction temperature exceeds 160_C, the device shuts down. In this mode switch Q1 and Q2 and the control circuits are all turned off. The device restarts in soft-start after the temperature drops below 135_C. This feature is provided to prevent catastrophic failures from accidental device overheating, and it is not intended as a substitute for proper heatsinking.
Low Dropout Operation
The NCP9001 offers a low input to output voltage difference. The NCP9001 can operate at 100% duty cycle. In this mode the PMOS (Q1) switches completely on. The minimum input voltage to maintain regulation can be calculated as:
VIN(min) + VOUT(max) ) (IOUT (RDS(on) ) RINDUCTOR))
(eq. 1)
When the EN pin has a voltage applied of less than 0.4 V, the NCP9001 will be disabled. In shutdown mode, the internal reference, oscillator and most of the control circuitries are turned off. Therefore, the typical current

APPLICATION INFORMATION
Output Voltage Selection
The output voltage is programmed through an external resistor divider connected from VOUT to FB then to GND. For low power consumption and noise immunity, the resistor from FB to GND (R2) should be in the [100 k-600 k] range. If R2 is 200 k given the VFB is 0.6 V, the current through the divider will be 3.0 mA. The formula below gives the value of VOUT, given the desired R1 and the R1 value:
VOUT + VFB (1 ) R1) R2
(eq. 2)
The corner frequency is given by:
fc + 1 2p L COUT + 1 2p 2.2 mH 10 mF + 34 kHz
(eq. 3)
* * * *
VOUT: Output Voltage (Volts) VFB: Feedback Voltage = 0.6 V R1: Feedback Resistor from VOUT to FB R2: Feedback Resistor from FB to GND
The device is intended to operate with inductance values between 1.0 mH and maximum of 4.7 mH. If the corner frequency is moved, it is recommended to check the loop stability depending on the output ripple voltage accepted and output current required. For lower frequency, the stability will be increased; a larger output capacitor value could be chosen without critical effect on the system. On the other hand, a smaller capacitor value increases the corner frequency and it should be critical for the system stability. Take care to check the loop stability. The phase margin is usually higher than 45.

Input Capacitor Selection
In PWM operating mode, the input current is pulsating with large switching noise. Using an input bypass capacitor can reduce the peak current transients drawn from the input supply source, thereby reducing switching noise significantly. The capacitance needed for the input bypass capacitor depends on the source impedance of the input supply. The maximum RMS current occurs at 50% duty cycle with maximum output current, which is IO, max/2. For NCP9001, a low profile, low ESR ceramic capacitor of 4.7 mF should be used for most of the cases. For effective bypass results, the input capacitor should be placed as close as possible to the VIN pin.

Inductor Selection
The inductor parameters directly related to device performances are saturation current and DC resistance and inductance value. The inductor ripple current (AIL) decreases with higher inductance:
V V DIL + OUT 1- OUT L fSW VIN
(eq. 4)
DIL peak to peak inductor ripple current L inductor value fSW switching frequency The saturation current of the inductor should be rated higher than the maximum load current plus half the ripple current:
DI IL(MAX) + IO(MAX) ) L 2
(eq. 5)
Output L-C Filter Design Considerations
The NCP9001 is built in 1.5 MHz frequency and uses current mode architecture. The correct selection of the output filter ensures good stability and fast transient response. Due to the nature of the buck converter, the output L-C filter must be selected to work with internal compensation. For NCP9001, the internal compensation is internally fixed and it is optimized for an output filter of L = 2.2 mH and COUT = 10 mF.
DIL(MAX) Maximum inductor current DIO(MAX) Maximum Output current The inductor's resistance will factor into the overall efficiency of the converter. For best performances, the DC resistance should be less than 0.3 W for good efficiency.

Output Capacitor Selection
Selecting the proper output capacitor is based on the desired output ripple voltage. Ceramic capacitors with low ESR values will have the lowest output ripple voltage and are strongly recommended. The output capacitor requires either an X7R or X5R dielectric. The output ripple voltage in PWM mode is given by:
DVOUT + DIL 4 1 fSW-3 COUT ) ESR (eq. 6)
Feed-Forward Capacitor Selection
In PFM mode (at light load), the output voltage is regulated by pulse frequency modulation. The output voltage ripple is independent of the output capacitor value. It is set by the threshold of PFM comparator.
The feed-forward capacitor sets the feedback loop response and is critical to obtain good loop stability. Given that the compensation is internally fixed, a fixed 18 pF or higher ceramic capacitor is needed. Choose a small ceramic capacitor X7R or X5R or COG dielectric.
