产品描述

The MP2315 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 MP2315 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 MP2315 requires a minimum number of readily available standard external components and is available in a space saving 8-pin TSOT23 package.

High-Efficiency, 3A, 24V, 500kHz, Sync. Step-Down Switch Evaluation Board

The EV2315-J-00A demonstrates MPS’s MP2315, a high-frequency, synchronous, rectified, step-down converter with built-in high-side and low-side power MOSFETs. The MP2315 offers a very compact solution to achieve a 3A continuous output current with excellent load and line regulation over a wide input supply range. The MP2315 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 includes over-current protection and thermal shutdown.

The MP2315 is available in a space-saving 8-pin TSOT23 package.
