G5904 Datasheet (Global Mixed-mode Technology) - Four Channel High Efficiency White LED Driver

G5904, Four Channel High Efficiency White LED Driver

The G5904 charge pump drives up to four white LEDs with regulated constant current for uniform intensity.

By utilizing dynamic 1x/2x charge-pump modes and ultra-low-dropout current regulators, it achieves high efficiency over the 1-cell lithium battery input voltage range.
