Ordering Information

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.
