DESCRIPTION

The MP8765 is a fully integrated high frequency

synchronous rectified step-down switch mode

converter. It offers very compact solutions to

achieve 6A continuous output current over a

wide input supply range with excellent load and

line regulation. The MP8765 operates at high

efficiency over a wide output current load range.

Constant-On-Time

(COT)

control

mode

provides fast transient response and eases loop

stabilization.

Under voltage lockout is internally set as 4.6 V,

An open drain power good signal indicates the

output is within its nominal voltage range.

Full protection features include OCP and thermal

shut down.

The converter requires minimum number of

external components and is available in QFN16

(3mmx3mm) package.
