Monolithic Power Systems MP38874

Beschreibung

The MP38874 is a monolithic step-down switch mode converter with a built in internal power MOSFET. It achieves 8A 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 MP38874 requires a minimum number of readily available standard external components and is available in a space saving 3mm x 4mm 14-pin QFN package.
