Description

The MP1474S is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a compact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input-supply range. The MP1474S has synchronous-mode operation for higher efficiency over the output current-load range.

Current-mode operation provides fast, transient response and eases loop stabilization.

Full protection features include over-current protection (OCP) and thermal shutdown (TSD).

The MP1474S requires a minimal number of readily available, standard, external components and is available in a space-saving 8-pin TSOT23 package.
