Description

General part information

MP2318 Series

The MP2318 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 2A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Full protection features include OCP and thermal shut down. The MP2318 requires a minimum number of readily available standard external components and is available in a space saving 8-pin TSOT23 package.Wide 4.5V to 24V Operating Input Range 2A Load Current 90mO/40mO Low Rds(on) Internal Power MOSFETs Low Quiescent Current High Efficiency Synchronous Mode Operation Fixed 2MHz Switching Frequency AAM Power Save Mode Internal Soft Start OCP Protection and Hiccup Thermal Shutdown Output Adjustable from 0.8V Available in an 8-pin TSOT-23 package
