DESCRIPTION

The MP2371 is a monolithic step-down switch

mode converter with a built-in internal power

MOSFET. It achieves 1.8A 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 MP2371 requires a minimum number of

readily available standard external components.

The MP2371 is available in a 2mm x 2mm QFN8

package.
