LP5526

Lighting Management Unit with High Voltage Boost

Converter with up to 150mA Serial FLASH LED Driver

General Description

Features

n High efficiency boost converter with programmable

output voltage up to 20V

LP5526 is a Lighting Management Unit for portable applica-

tions. It is used to drive display backlights, keypad LEDs,

RGB LEDs and camera flash LEDs. LP5526 can drive 2

separately connected strings of LEDs with high voltage

boost converter. The RGB driver allows driving either indi-

vidual color LEDs or RGB LED from separate supply power,

or it can be used to drive series connecter flash LEDs from

high voltage boost converter.

n 2 individual drivers for serial display backlight LEDs

n Automatic dimming controller

n Stand alone RGB controller

n Dedicated flash function

n Safety function to avoid prolonged flash

n 3 general purpose IO pins

The backlight drivers (MAIN and SUB pins) are both high

resolution constant current mode drivers. The flash outputs

can drive series connected flash LED with up to 150mA of

current. External PWM control can be used for dimming any

selected LED outputs or it can be used to trigger the flash.

The flash has also 1-second safety timer.

The device is controlled through 2-wire low voltage I²C

compatible interface that reduces the number of required

connections.

n 25-bump micro SMD Package: (2.54mm x 2.54mm x

0.6mm)

Applications

n Cellular Phones and PDAs

n MP3 Players

n Digital Cameras
