FAN5624UMPX

The FAN5624 is four 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 IOW dropout Of 50 mV allows driving LEOS Without any inductors 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 LEDS through this interface by applying digital pulses. The FAN562x family Of LED drivers provides high effciency due to the IOW 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, ID-lead UMLP, and 10-lead MicroPakT MCP, respectively.
