DESCRIPTION

The EV9151-D-00A is for demonstrating MPS’s

MP9151,

a

high-frequency,

synchronous,

rectified,

step-down,

switch-mode converter

with internal power MOSFETs. MP9151 offers a

very compact solution to achieve 4A continuous

output current over a wide input supply range

with excellent load and line regulation. The

MP9151 operates at high efficiency over a wide

output current load range.

Current-mode operation provides fast transient

response and eases loop stabilization. The full

protection

features

include

over-current

protection and thermal shutdown.

The MP9151 requires a minimal number of

readily-available standard external components

and comes in a space saving 2×3mm 14-pin

QFN package.
