Description

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 modeoperation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown.The MP28367 requires a minimum number of readily available standard external components. The MP28367 is available in TSOT23-6 packages.
