Monolithic Power Systems MP38900-B

Beschreibung

The MP38900/MP38900-B is a fully integrated, high frequency synchronous rectified step-downn switch mode converter. It offers a very compactsolution to achieve 10A continuous output current over a wide input supply range with excellent load and line regulation. The MP38900/MP38900-B operates at high efficiency over a wide output current load range.

To futher optimize efficiency at light load, the VCC supply of MP38900 is designed to be biased externally.Constant-On-Time (COT) control mode provides fast transient response and eases loop stabilization.Full protection features include SCP, OCP, OVP,UVP and thermal shutdown.The MP38900/MP38900-B requires a minimum number of readily available standard external components and is available in a space-saving QFN20 (3x4mm) package.
