LP5524

Parallel LED Driver with PWM Brightness Control in Micro

SMD Package

General Description

The LP5524 is a highly integrated dual-zone LED driver that

can drive up to four LEDs in parallel with a total output current

of 100mA. Regulated high side internal current sources de-

liver excellent current and brightness matching in all LEDs.

LED driver current sources are split into two independently

controlled banks for driving secondary displays, keypad and

indicator LEDs. Brightness control is achieved by applying

PWM signals to each enable pin. Default LED current is fac-

tory-programmable and an optional external resistor can be

used to set LED current to user programmable values.

Features

High side LED driver

■

Drives 4 LEDs with Up to 25mA per LED

Ultra-Small Solution Size:
