FAN5622 - 2-channel Linear LED Driver

Datasheet Summary

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.

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 Digital Control Interface for Easy Programming.
  • 32 Linear Steps of Dimming Control Less than 1µA Shut-Down Current Short-Circuit, Under-Voltage, and Thermal Protection Wide Input Voltage Range.
