1. DESCRIPTION

The MP2234SGJ-Z 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 MP2234SGJ-Z 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 shut down (TSD). The MP2234SGJ-Z requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package.
