PIN ASSIGNMENT
PIN 1 2 Name C1P GND Type POWER POWER Description One side of the external charge pump capacitor (CFLY ) is connected to this pin, associated with C1N, pin 12 (Note 1). This pin is the GROUND signal for the analog and digital blocks and must be connected to the system ground. This pin is the GROUND reference for the DC/DC converter and the output current control. The pin must be connected to the system ground, a ground plane being strongly recommended. This pin sinks to ground and monitors the current flowing into the LED3, intended to be used in illumination application (Note 2). The Anode of the associated LED shall be connected to the Vout pin. This pin sinks to ground and monitors the current flowing into the LED2, intended to be used in illumination application (Note 2). The Anode of the associated LED shall be connected to the Vout pin. This pin sinks to ground and monitors the current flowing into the LED1, intended to be used in illumination application (Note 2). This pin copies the Analog Ground and must be connected to the system ground plane. This pin carries the data provided by the I2C protocol. The content of the SDA byte is used to program the mode of operation and to set up the output current (Note 1). This pin provides the reference current, based on the internal band-gap voltage reference, to control the output current flowing in the LED. A 1% tolerance, or better, resistor shall be used to get the highest accuracy of the LED biases. An external current mirror can be used to bias this pin to dynamically set up the I-LED peak current. In no case shall the voltage at IREF pin be forced either higher or lower than the 600 mV provided by the internal reference. This pin carries the I2C clock to control the Charge Pump converter and to set up the output current. The SCL clock is associated with the SDA signal. This pin provides the output voltage supplied by the Charge Pump converter. The Vout pin must be bypassed by 1 mF ceramic capacitor located as close as possible to the VOUT pin to properly bypass the output voltage to ground. The circuit shall not operate without such bypass capacitor connected across the Vout pin and Ground (Note 1). The output voltage is internally clamped to 5.5 V maximum in the event of a no load situation. On the other hand, the output current is limited to 40 mA (typical) in the event of a short circuit to ground. This pin is the input Battery voltage to supply the analog and digital blocks. The pin must be decoupled to ground by a 1mF or higher ceramic capacitor (Note 1). One side of the external charge pump capacitor (CFLY ) is connected to this pin, associated with C1P, pin 1 (Note 1)

DC/DC OPERATION
The converter is based on a charge pump technique to generate a DC voltage capable to supply the RGB LED load. The system regulates the current flowing into each LED, not the DC Vout value, by means of internal current mirrors associated with the diodes. Consequently, Vout = Vbat * Mode, with Mode = 1 or Mode = 2, the extra voltage Vout - Vf being sustained by the current mirror structure. The average forward current of each LED can be independently programmed (by means of the associated PWM ) to achieve the RGB function. The maximum LED current, setup by the external bias resistor connected across IREF pin and Ground, is associated to the digital content of the I2C register (see Table 1). This peak current applies to the three LED simultaneously, but, thanks to the RGB function, the average output current of each LED is controlled by the independent PWM controllers. Consequently, the luminosity of each RGB diode can be independently adjusted to cope with a given illumination need. Since the peak current is constant, the color of the RGB diodes is the one defined by the specifications of each individual LED. The built-in OVP circuit continuously monitors the Vout voltage and stops the converter when the voltage is above 5.7 V. The converter resumes to normal operation when the voltage drops below 4.4 V (no latch-up mechanism). Consequently, the chip can operate under no load conditions during any test procedures.
LOAD CURRENT CALCULATION
optimize the tolerance of the output current. Although it is possible to use higher or lower value, as defined in the analog section, a 48 kW / 1% resistor will provide the best compromise, the dimming being performed by the appropriate PWM registers. On the other hand, care must be observed to avoid leakage current flowing into either the IREF pin of the bias resistor network. Finally, for any desired ILED current, the curve provided Figure 4 can be recalculated according to the equation:
ILED + IREF @ k 31 * n ILED +
Vref R
(eq. 1) (eq. 2)
@ 2400 31 * n
with: n = step value @ 1 n 31 with: R = reference resistance with: k = internal multiplier constant = 2400 Note: n = 0 forces ILED to zero with: n = 30 and n = 31 yields the same LED current
LOAD CONNECTION
The load current is derived from the 600 mV reference voltage provided by the internal Band Gap associated to the external resistor connected across IREF pin and Ground. Note : due to the internal structure of this pin, no voltage, either downward or upward, shall be forced at the IREF pin. The reference current is multiplied by the constant k = 2400 to yield the output load current. Since the reference voltage is based on a temperature compensated Band Gap, a tight tolerance resistor will provide a very accurate load current. The resistor is calculated from the Ohm's law (Rbias = Vref/IREF) and a more practical equation can be arranged to define the resistor value for a given maximum output current: Rbias = (Vref*k)/Iout [1] Rbias = (0.6*2400)/Iout [2] Rbias = 1440/Iout Since the Iref to ILED ratio is very high, it is strongly recommended to set up the reference current at 12.5 mA to
The primary function of the NCP5623B is to control three LED arranged in the RGB color structure (reference OSRAM LATB G66x). The brightness of each LED is independently controlled by a set of dedicated PWM structure embedded into the silicon chip. The peak current, identical for each LED, is programmable by means of the I2C data byte. With 32 steps per PWM, the chip provides 32768 colors hue in a standard display. Moreover, a built-in gradual dimming provides a smooth brightness transition for any current level, in both Upward and Downward direction. The dimming function is controlled by the I2C interface: see Table 2. The NCP5623B chip is capable to drive the three LED simultaneously, as depicted in Figure 1, but the load can be arranged to accommodate several LED if necessary in the application. Finally, the three current mirrors can be connected in parallel to drive a single power full LED, thus yielding 90 mA current capability in a single LED.
I2C PROTOCOL
The NCP5623B is programmed by means of the standard I2C protocol controlled by an external MCU. The communication takes place with two serial bytes sharing the same I2C frame: - Byte#1 physical I2C address - Byte#2 Selected internal registers & function

11. The programmed current applies to the three LED simultaneously, the gradual dimming is not engaged 12. The bit values represent the steps count, not the ILED current: see equations 1 & 2, page 7, to derive the ILED value.
GRADUAL DIMMING
The purpose of that function is to gradually Increase or Decrease the brightness of the backlight LED upon command from the external MCU. The function is activated and controlled by means of the I2C protocol. In order to avoid arithmetic division functions at silicon level, the period (either upward or downward) is equal to the time defined for each step, multiplied by the number of steps. To operate such a function, the MCU will provide three information: 1 - The target current level (either upward or downward) 2 - The time per step
3 - The Upward or Downward mode of operation When a new gradual dimming sequence is requested, the output current increases, according to an exponential curve, from the existing start value to the end value. The end current value is defined by the contain of the Upward or Downward registers, the width of each step is defined by the third register, the number of step being in the 1 to 30 range. In the event of software error, the system checks that neither the maximum output current (30 mA), nor the zero level are forced out of their respective bounds. Similarly, software errors shall not force the NCP5623B into an uncontrolled mode of operation.

The dimming is built with 30 steps and the time delay encoded into the second byte of the I2C transaction: see Table 1. When the gradual dimming is deactivated (B7 = B6 = 0, B5 = 1), the output current is straightforwardly set up to the level defined by the contain of the related register upon acknowledge of the output current byte.

The gradual dimming sequence must be set up before a new output current data byte is send to the NCP5623B . At this point, the brightness sequence takes place when the new data byte is acknowledged by the internal I2C decoder. Since the six registers are loaded on independent byte flow associated to the I2C address, any parameter of the NCP5623B chip can be updated ahead of the next function as depicted in Table 2.

The number of step for a given sequence, depends upon the start and end output current range: since the IPEAK value is encoded in the Bits[4:0] binary scale, a maximum of 31 steps is achievable during a gradual dimming operation. The number of steps will be automatically recalculated by the chip according to the equation: Nstep = | existing step position - new step position | As an example, assuming the previously programmed step was 5 and the new one is 15, then we will have 10 steps to run between the actual location to the end value.

The built-in PWM are fully independent and can be programmed to any value during the normal operation of the NCP5623B chip. The PWM operate with five bits, yielding a 32 steps range to cover the full modulation (0 to 100%) of the associated LED: - PWM = $00 the associated LED is fully OFF, whatever be the programmed ILED value - PWM > $00 but < $1F the brightness of the associated LED is set depending upon the PWM modulation value - PWM = $1F the associated LED is fully ON, the current being the one defined by the ILED value. Each PWM is programmable, via the I2C port as depicted, at any time under any sequence arrangement as requested by the end system's designer. The PWM does not change the ILED value, but merely modulate the ON/OFF ratio of the associated LED. Each step of the PWM represent 100/32 = 3.125% of the full range, the clock being 2.1 kHz (typical).
