CP2137 Datasheet (CHIP) - 4-Channel LED Driver

CP2137, 4-Channel LED Driver

The CP2137 is optimized for white LED supplies in backlight color display applications.

The device provides a constant current, set by an external resistor, for each LED.

The supply voltage ranges from 2.7 V to 5.5 V and is ideally suited for all applications powered by a single LI-Ion battery cell
