Monolithic Power Systems MP8725

Description

The MP8725 is a high frequency synchronous rectified step-down switch mode converter with built in internal power MOSFETs. It offers a very compact solution to achieve 5A continuous output current over a wide input supply range with excellent load and line regulation. The MP8725 operates at high efficiency over a wide output current load range.Current mode operation provides fast transient response and eases loop stabilization.Full protection features include OCP and thermal shut down.The MP8725 requires a minimum number of readily available standard external components and is available in a space saving 3mm x 4mm 14-pin QFN package.
