DESCRIPTION

The

EVM3686-RU-00A

is

used

for

demonstrating

the

performance

of

MPS’

MPM3686, a 20A step-down power module

with

built-in

power

MOSFETs

and

power

inductor.

High power efficiency over a wide load range is

achieved

by

scaling

down

the

switching

frequency at light load to reduce the switching

related loss by constant on time control. Over-

Current-Protection,

Over-Voltage

Protection,

Under-Voltage

Protection,

and

thermal

shutdown provide reliable operation.

MPM3686 is available in QFN 12x15x4mm

package.
