LP5527

Tiny LED Driver for Camera Flash and 4 LEDs with I²C

Programmability, Connectivity Test and Audio

Synchronization

General Description

Features

n High current boost DC-DC converter (up to 1A output

current)

The LP5527 is a lighting management unit for handheld

devices with I²C compatible control interface. The LP5527

has a step-up DC/DC converter with high current output and

it drives display and keypad backlights and powers the cam-

era flash LED. In addition the DC/DC converter has the

output current to power for example an audio amplifier si-

multaneously. The chip has four 8-bit programmable high

efficiency constant current LED drivers and a FLASH LED

driver. Built-in audio synchronization feature allows the user

to synchronize one of the LEDs to audio input.

n Programmable boost output voltage

n 400 mA flash LED constant current driver with low

tolerance and a safety circuit

n Synchronization pin for the flash timing

n Two single-ended audio inputs with gain control

n Four constant current 15 mA LED drivers with 8-bit

programmable brightness control

n Audio synchronization feature

The LP5527 has an integrated 400 mA flash driver with a

safety stop feature and 50 mA torch mode. An external

enable pin is provided for the synchronizing the flash with the

camera action. An external software independent test inter-

face provides a fast way to find a broken path or short on

LED circuits. Very small microSMD package together with

minimum number of external components is a best fit for

handheld devices.

n I²C compatible control interface

n Built-in LED connectivity test to maximize manufacturing

yield

n Small microSMD-30 package (2.5 mm x 3.0 mm x 0.6

mm)

Applications

n Camera FLASH, funlight and backlight driving in battery

powered devices

Typical Application
