DESCRIPTION

The MPM3650 is a fully integrated highfrequency,

synchronous, rectified, step-down

power module with an internal inductor. It offers

a highly compact solution to achieve 6A of

continuous output current (IOUT) across a wide

input voltage (VIN) range, with excellent load and

line regulation. The MPM3650 offers

synchronous mode for high efficiency across the

entire output current load range.

Constant-on-time (COT) control provides fast

transient response, easy loop design, and tight

output regulation.

Full protection features include short-circuit

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

under-voltage protection (UVP), and thermal

shutdown.

The MPM3650 requires a minimal number of

readily available, standard external components,

and is available in a space-saving QFN-24

(4mmx6mm) package.
