NCP5604A Datasheet (ON Semiconductor) - High Efficiency White LED Driver

NCP5604A, High Efficiency White LED Driver

Pin 1 2 Symbol VBAT EN Type INPUT, POWER INPUT, DIGITAL Description Input Battery voltage to supply the analog and digital blocks.

The pin must be decoupled to ground by a 1.0 mF ceramic capacitor.

This pin carries the Enable function to control the DC *DC converter.

It can be used to digital

www.DataSheet4U.com 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%
