MP1496S

The MP1496S 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 MP1496S 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 and thermal shut down and external SS control. 
The MP1496S requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package.
