MP2314 High Efficiency 2A, 24V, 500kHz Synchronous Step Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP2314 is a high frequency synchronous Wide 4.5V to 24V Operating Input Range rectified step-down switch mode converter with 2A Load Current built in internal power MOSFETs. It offers a 120m/50m Low Rds(on) Internal Power very compact solution to achieve 2A continuous MOSFETs output current over a wide input supply range Low Quiescent Current with excellent load and line regulation. The High Efficiency Synchronous Mode MP2314 has synchronous mode operation for Operation higher efficiency over output current load range. Fixed 500kHz Switching Frequency Frequency Sync from 200kHz to 2MHz Current mode operation provides fast transient External Clock response and eases loop stabilization. AAM Power Save Mode Full protection features include OCP and Internal Soft Start thermal shut down. OCP Protection and Hiccup The MP2314 requires a minimum number of Thermal Shutdown readily available standard external components Output Adjustable from 0.8V and is available in a space saving 8-pin Available in an 8-pin TSOT-23 package TSOT23 package.
