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. The 250kHz fixed frequency switching allows for tiny external components, and the regu.
