RT9396

I²C Interface PMIC with 6-Channel WLED Driver and 4-LDO

General Description

Features

^zTri-Mode (x1/x1.5/x2) Charge Pump

^zMaximum 25mA x 6-Channel LED Backlighting

Output Current

The RT9396 is a power management IC (PMIC) for

backlighting and phone camera applications. The PMIC

contains a 6-Channel charge pump white LEDdriver and

four low dropout linear regulators.

^zSupport Main/Sub (4+2/5+1) LED Function

^z64 Steps Programmable LED Current

^zSupport PWM Dimming Function

^zFade In/Out Via I²C Control

The charge pump drives up to 6 white LEDs with regulated

constant current for uniform intensity. Each channel

(LED1 to LED6) supports up to 25mA of current. These

6-Channels can be also programmed as 4 plus 2-Channels

or 5 plus 1-Channel with different current setting for

auxiliary LEDapplication. The RT9396 maintains highest

efficiency by utilizing a x1/ x1.5/ x2 fractional charge pump

and low dropout current regulators.An internal 6-bitDAC

is used for backlight brightness control. Users can easily

configure up to 64 steps of LEDcurrent via the I²C interface

control.

^z4 Low Dropout Regulators

^zMaximum 200mA x 4-Channel LDO Output Current

^z16-Level LDO Output Voltage Setting

^zI²C Programmable Independent LDO Channel

ON/OFF Control

z Over Temperature Protection

z Thin 24-Lead WQFN Package

z RoHS Compliant and Halogen Free

The RT9396 also comprises low noise, low dropout

regulators, which provide up to 200mAof current for each

of the four channels. The four LDOs deliver 3% output

accuracy and low dropout voltage of 200mV @ 200mA.

Users can easily configure LDO output voltage via the I²C

interface control. The LDOs also provide current limiting

and over temperature functions.

Applications

z Cellular Phones

z PDAs and Smart Phones
