DESCRIPTION

The

MP8758

is

a

fully-integrated,

high

frequency, synchronous, rectified, step-down

converter. It offers a very compact solution to

achieve a 10A output current over a wide input-

supply range with excellent load and line

regulation.

MP8758 employs the Constant-On-Time (COT)

control scheme, which provides fast transient

response, eases loop stabilization. The COT

control scheme provides seamless transition to

PFM mode at light load operation which boosts

the light load efficiency.

Under voltage lockout is internally set as 4.5V.

An open drain power good signal indicates

output voltage is within its nominal voltage

range.

Full protection features include OCP, OVP, and

thermal shutdown.

MP8758 requires minimum number of external

components and are available in QFN21

(3mmx4mm) package.
