RT9367C I2C Programmable White LED Driver with Dual LDO General Description The RT9367C is an integrated solution for backlighting and phone camera input supply. The part contains a charge pump white LED driver and dual low dropout linear regulators. This IC can be shutdown by pulling ENA low. In the section of charge pump, The RT9367C can power up 4 white LEDs with regulated constant current for uniform intensity. Each channel (LED1-LED4) can support up to 25mA. The part maintains highest efficiency by utilizing a x1/x1.5/x2 fractional charge pump and low dropout current regulators. An internal 5-bit DAC is used for brightness control. Users can easily configure up to 32step of LED current by I2C interface.
