High Efficiency, 7A, 18V
Synchronous, Step-Down Converter
The MP8757 is a fully-integrated, high
frequency, synchronous, rectified, step-down
converter. It offers a very compact solution to
achieve a 7A output current over a wide input-
supply range with excellent load and line
MP8757 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
Full protection features include OCP, OVP, and
thermal shut down.
MP8757 requires minimum number of external
components and are available in QFN21
