DESCRIPTION

The MPM3860 is a fully integrated, highfrequency,

synchronous, rectified, step-down,

power module with internal inductor. It offers a

very compact solution to achieve 6A of

continuous output current over a wide input

range, with excellent load and line regulation.

The MPM3860 has synchronous mode

operation for higher efficiency over the output

current load range.

Constant-on-time (COT) control operation

provides very fast transient response and easy

loop design, as well as very tight output

regulation.

Full protection features include short-circuit

protection (SCP), over-current protection (OCP),

under-voltage protection (UVP), and thermal

shutdown.

The MPM3860 requires a minimal number of

readily available, standard external components,

and is available in a space-saving QFN-24

(4mmx6mm) package.
