Monolithic Power Systems MP8652

Beschreibung

The MP8652 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 MP8652 requires a minimum number of readily available standard external components and is available in a 20-pin 3mm x 4mm QFN package.The MP8652 is ideal for a wide range of applications including distributed power systems, pre-regulator for linear regulators, compact DC- DC regulators for PCB space limited platforms.
