RT9363A

3 Channels 90mA x1/x2 Charge Pump White LED Driver

General Description

Features

^zOver 80% Average Efficiency Over Battery Life

The RT9363A is a compact, high efficient and highly

integrated charge pump white LEDdriver. It maintains the

highest efficiency by utilizing a x1/x2 fractional charge

pump and low dropout current regulators. The RT9363A

supports up to 3 white LEDs and regulates a constant

current for uniform intensity. The part implements a 4-bit

DAC for brightness control. Users can select external R_SET

or internal R_SETby ISET pin. 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. The part can support 15mAto 30mAfor the 100%

current setting. Users also can use the internal R_SETfor

100% current setting of 20mA just by connecting the ISET

pin to V_IN. The operating voltage range is from 2.8V to

5.5V. Internal soft start circuitry effectively reduces the in-

rush current while both start-up and mode transition. The

load is disconnected from V_INwhile shutdown and the

shutdown current is less than 1uA.
