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%.
