FAN5622 Datasheet (Fairchild Semiconductor) - 2-channel Linear LED Driver

FAN5622, 2-channel Linear LED Driver

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.

FAN5622 Features

* Family of Three Linear Current-Sink LED Drivers that Support 2, 4, or 6 LED Outputs Current Sink Driver for Each LED Output:

* 30mA Maximum Output Current

* 50mV Drop-out at 15mA IOUT

* Better than 3% Matching between Channels

* External RSET Single-Wire D
