Monolithic Power Systems MP8706

Description

The MP8706 is a high frequency synchronous rectified step-down switch mode converter with built in internal power MOSFETs. It offers avery compact solution to achieve 3A continuous output current over a wide input supply range with excellent load and line regulation. TheMP8706 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 MP8706 requires a minimum number of readily available standard external components and is available in a space saving 8-pin SOICpackage with an exposed pad.
