FAN5624 Datasheet 2-channel Linear Led Driver

Manufacturer: Fairchild (now onsemi)

Overview: DataSheet.in FAN5622/24/26 — Linear LED Drivers with Single-Wire Digital Interface May 2010 FAN5622 / FAN5624 / FAN5626 Linear LED Drivers with Single-Wire Digital.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The FAN5622, FAN5624, and FAN5626 are two-, four-, and six- channel current-sink linear LED drivers used to backlight the main LCD displays or keypads in mobile electronics, such as cellular phone handsets.

A very low dropout of 50mV allows driving LEDs without any inductors or switch capacitors.

The brightness levels of the LED outputs are programmed through single-wire digital control interface.
