MP3389EF Datasheet – 12-Channel, Step-up White LED Driver

Part Number: MP3389EF, 3389EF

Function: 12-String, Step-up White LED Driver

Package: TSSOP28 type

Manufacturer: MPS ( Monolithic Power Systems )


MP3389EF controller


The MP3389EF is a step-up controller with 12-channel 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. It drives an external MOSFET to boost up the output voltage from a 5V to 28V input supply. The MP3389 regulates the current in each LED string to the programmed value set by an external current setting resistor.
