Monolithic Power Systems MP28275

Beschreibung

The MP28275 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 with excellent load and line regulation. The MP28275 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 MP28275 requires a minimum number of readily available standard external components and is available in a space saving 3mm x 4mm 14-pin QFN package.
