The MP38876 is a monolithic step-down switch mode converter with a built in internal power MOSFET. It achieves 15A 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 and thermal shutdown. The MP38876 requires a minimum number of readily available standard external components and is available in a 20-pin 3mm x 4mm QFN package. The MP38876 is ideal for a wide range of applications including distributed power systems, pre-regulator for linear regulators, compact DCDC regulators for PCB space limited platforms.Wide 4.5V to 28V Operating Input Range 15A Output Current 25m?
