RT9367C

I²C Programmable White LED Driver with Dual LDO

General Description

Features

^ꢀAn Integrated Solution for Backlighting and Phone

The RT9367C is an integrated solution for backlighting

and phone camera input supply. The part contains a charge

pump white LED driver and dual low dropout linear

regulators. This IC can be shutdown by pulling ENA low.

Camera Input Supply

^ꢀI²C Programmable, 32 Steps Dimming Control and

Independent Channel On/Off Control

^ꢀOver Temperature Protection

In the section of charge pump, The RT9367C can power

up 4 white LEDs with regulated constant current for uniform

intensity. Each channel (LED1-LED4) can support up to

25mA. The part maintains highest efficiency by utilizing

a x1/x1.5/x2 fractional charge pump and low dropout

current regulators. An internal 5-bit DAC is used for

brightness control. Users can easily configure up to 32-

step of LED current by I²C interface.

^ꢀPower On Reset for Data Register

^ꢀTypical 1uA Low Shutdown Current with Interface

Fully On

^ꢀCharge Pump White LED Driver

` Over 93% Peak Efficiency Over Li-ion Battery

Discharge

` Typical 85% Average Efficiency Over Li-ion Battery

Discharge

In the section of linear regulator, The RT9367C comprises

a dual channel, low noise, and low dropout regulator

sourcing up to 300mAat each channel. The range of output

voltage can be configured from 1.1V to 3.3V by I²C

interface. The outputs of LDO offer 3% accuracy and low

dropout voltage of 250mV @300mA. The LDO also

provides current limiting and output short circuit thermal

folded back protection.
