The MP1499 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 peak output current over a wide input supply range with excellent load and line regulation. The MP1499 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 over current protection and thermal shut down. The MP1499 requires a minimum number of readily available standard external components and is available in a space saving 10-pin QFN (2x3mm) package.
