MP1494S

2A, 16V, 500kHz, High-Efficiency Step-Down Converter

Datasheet

Description

The MP1494S is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input supply range. The MP1494S 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 and thermal shut down. The MP1494S requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package.
