Monolithic Power Systems MP8718

Beschreibung

The MP8718 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 4A continuous output current over a wide input supply range with excellent load and line regulation. The MP8718 has synchronous mode operation for higher efficiency over 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 MP8718 requires a minimum number of readily available standard external components and is available in a space saving 8-pin SOIC package with an exposed pad.
