RT9368 4-Channel Charge Pump White LED Driver with Low Dropout Current Source General Description The RT9368 is a high efficiency and cost effective charge pump white LED driver. It supports up to 4 white LEDs with regulated constant current for uniform intensity. The RT9368 maintains the highest efficiency by utilizing a x1/ x1.5/x2 charge pump and low dropout current regulators. User can easily configure each LED current from 1.25mA to 20mA by a PWM dimming control. The dimming of white LEDs current can be achieved by applying a PWM signal to the EN pin. RT9368 is available in a WQFN 3x3-16L package.
