MP1497DJ-LF-Z (High-Efficiency, 3A, 16V, 500kHz Synchronous, Step-Down Converter)

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.
