RT9363

Smallest 60mA 3-Channel Charge Pump White LED Driver

with Low Dropout Current Source

General Description

Features

^zVery High Efficiency Over 80% of Battery Life

The RT9363 is a high efficiency and cost effective charge

pump white LED driver. It supports up to 3 white LEDs

with regulated constant current for uniform intensity. The

RT9363 maintains the highest efficiency by utilizing a

x1/x2 charge pump and low dropout current regulators.

^zSupport up to 3 White LEDs

^zSupport up to 60mA Output Current

^z1% Typical LED Current Matching

^zSoft Start Function

^zShort Circuit Protection Function

^zAuto Charge Pump Mode Selection

^z250kHz Fixed Frequency Oscillator

^zOutput Over Voltage Protection

^z16-Step Brightness Control

User can easily configure each LEDcurrent up to 20mAby

a pulse dimming control. The dimming of white LEDs

current can be achieved by applying a pulse signal to the

EN pin. There are totally 16 steps of current could be set

by users.

^zLow Input Noise and EMI

The operating voltage range is 2.8V to 5.0V. Internal soft

start circuitry effectively reduces the inrush current while

both start-up and mode transition. RT9363 also provides

comprehensive protections such as short circuit protection.

The load is disconnected from VIN while shutdown and

the shutdown current is less than 10μA.

z RoHS Compliant and 100% Lead (Pb)-Free

Applications

z Mobile Phone, DSC, MP3

z White LED Backlighting

z LCDDisplay Supply

RT9363 is available in a TSOT-23-8 package (1.0mm max

height).
