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. 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 drop-out voltage of the LED driver.
Good matching between different channels of LED output is
provided across the entire 32 dimming steps. These LED
drivers also integrate short circuit, under-voltage, and thermal
protection to ensure for a more robust solution.
The FAN5622, FAN5624, and FAN5626 are available in very
small form-factor packages: 6-pin Super SOT23, 10-lead
UMLP, and 10-lead MicroPak™ MLP, respectively.
