Linear LED Drivers with Single-Wire Digital Interface
FAN5622, FAN5624, FAN5626
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 50 mV allows driving LEDs without any inductors or switch
capacitors.
The brightness levels of the LED outputs are programmed through single−wire digital control interface.
The user can program 32 linear dimming steps and turn on and off the LEDs through this interface by applying digital pulses.
The FAN562x family of linear LED drivers provides high efficiency due to the low...
