Product Information

The MP2225 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 5A output current with excellent load and line regulation over a wide input supply range. The MP2225 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 MP2225 requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package.

Symmetry Electronics is an authorized Monolithic Power Systems distributor.
