MPS : MPM3682 – 18V 10A Step Down Power Module in 12 x 12 x 4mm QFN

Power Regulation, Conversion and Management

The MPM3682 is an easy-to-use fully integrated 10A step down DC/DC power module. It integrates the DC/DC converter, power inductor, input/output capacitors and the necessary resistors/capacitors in a compact QFN 12 x 12 x 4mm package.

This total power solution needs as few as two external components (one resistor and one capacitor) to work. MPM3682 can deliver 10A output current over a wide input supply voltage range with excellent load and line regulation. It implements Constant-On-Time (COT) control to provide fast transient response and ease the loop stabilization.
