DESCRIPTION
The MP8650 is a monolithic step-down switch
mode converter with a built in internal power
MOSFET. It achieves 15A 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 MP8650 requires a minimum number of
readily available standard external components
and is available in a 20-pin 3mm x 4mm QFN
package.
The MP8650 is ideal for a wide range of
applications including distributed power systems,
pre-regulator for linear regulators, compact DC-
DC regulators for PCB space limited platforms.
