MP4001 Overview
Description
The MP4001 is a high efficiency step-down converter designed for driving the high brightness Light Emitting Diodes (LEDs). The MP4001 drives external MOSFET with boundary conduction mode which features no reverse recovery loss in the freewheeling diode, soft turn on with zero-current and valley voltage for the power MOSFET.
