DESCRIPTION

The MP2357 is a monolithic step-down switch

mode converter with a built-in internal power

MOSFET. It achieves a 0.5A peak 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 MP2357 requires a minimum number of

readily available standard external components.

The MP2357 is available in TSOT23-6 and

SOT23-6 packages.
