MP1409

The MP1409 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves 2A 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 cyclebycycle current limiting and thermal shutdown. In shutdown mode the regulator draws 25μA of supply current.The MP1409 requires a minimum number of readily available standard external components.
