MP8671
10A, 25V, 600KHz Step-Down Converter
with Synchronizable Gate Driver
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP8671 is a monolithic step-down switch
mode converter with a built in internal power
MOSFET. It achieves 10A continuous output
current over a wide input supply range with
excellent load and line regulation.

Current mode operation provides fast transient
response and eases loop stabilization.
Fault condition protection includes cycle-by-cycle
current limiting and thermal shutdown.
The MP8671 requires a minimum number of
readily available standard external components
and is available in a space saving 3mm x 4mm
14-pin QFN package.
