FAN5624: Linear LED Driver, 4-channel, with Single-wire Digital Interface

Description: The FAN5624 is a four-channel current-sink linear ...
  • The FAN5624 is a four-channel current-sink linear LED driver used to backlight the main LCD display or keypad 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 FAN5624 linear LED driver 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.
