Description

The MP1497 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 3A continuous output current with excellent load and line regulation over a wide input supply range. The MP1497 has synchronous mode operation for higher efficiency over the output current load range. Current-mode operation provides a fast transient response and eases loop stabilization. Protective features include over-current protection, thermal shutdown, and external SS control. The MP1497 requires a minimal number of readily-available external components and is available in a space-saving 8-pin TSOT23 package.
