Conv DC-DC 4.75V to 23V Step Down Single-Out 1.23V to 16V 1.5A 10Pin QFN T/R
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
