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.
