MP2259 Datasheet (MPS) - Step-Down Converter

MP2259, Step-Down Converter

The MP2259 is a monolithic integrated stepdown switch mode converter with an internal power MOSFET.

It achieves 1A 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.
