产品描述

The MP2315S is a high-efficiency, synchronous, rectified, step-down, switch mode converter with built-in, internal power MOSFETs. It is a next generation of the MP2315. 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 MP2315S uses 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), over-voltage protection (OVP), and thermal shutdown. The MP2315S requires a minimal number of readily available, standard, external components and is available in a compact TSOT23-8 package.
