MP28367 - MPS

MP28367 Step-Down Converter

The MP28367 is a monolithic step-down switch mode converter with a built-in internal power MOSFET. It achieves 1A peak 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 .
