DESCRIPTION

The MP2351 is a monolithic step down switch mode converter with a built in internal power MOSFET. It achieves 1.5A 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, short circuit frequency foldback and thermal shutdown. In shutdown mode the regulator draws 20μA of supply current.

The MP2351 requires a minimum number of readily available standard external components
