MP3389 Datasheet (MPS) - Step-up White LED Driver

MP3389, Step-up White LED Driver

The MP3389 is a step-up controller with 12channel current sources designed for driving the WLED arrays for large size LCD panel backlighting applications.

The MP3389 uses current mode, fixed frequency architecture.

The switching frequency is programmable by an external frequency setting resistor.
