4-Channel Charge Pump White LED Driver with Low

Dropout Current Source

General Description

Features

^zVery High Efficiency Over 80% of Battery Life

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.

^zSupport up to 4 White LEDs

^zSupport up to 80mA Output Current

^z1% Typical LED Current Matching

^zSoft Start Function

^zAuto Charge Pump Mode Selection

^z250kHz Fixed Frequency Oscillator

^zOutput Over Voltage Protection

^zPWM Dimming Control

User can easily configure each LEDcurrent 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.

^zLow Input Noise and EMI

RT9368 is available in a WQFN3x3-16L package.

^zRoHS Compliant and 100% Lead (Pb)-Free
