NCP5604A, NCP5604B

High Efficiency White LED

Driver

The NCP5604A and NCP5604B products are multiple output LED

drivers dedicated to the display back light. The NCP5604A drives up

to 4 LEDs, the NCP5604B version being dedicated to the three LED

applications.

The two parts share a common built−in DC/DC converter, based on

a charge pump structure, including the new 1.33X mode of operation,

improving the efficiency over the full input battery supply voltage

span over 90%.
