MP2234
General Description
The MP2234 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 over a
wide input supply range with excellent load and line regulation. The MP2234 has synchronous mode operation
for higher efficiency over output current load range. Current mode operation provides fast transient response
and eases loop stabilization. Full protection features include OCP and thermal shut down. The MP2234 requires
a minimum number of readily available standard external components and is available in a space saving 8-pin
TSOT23 package.
