Description

The EV2338 Evaluation Board is designed to demonstrate the capabilities of MPS’ MP2338. The MP2338 is a fully integrated high frequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 3A continuous output current over a wide input range, with excellent load and line regulation. The MP2338 has synchronous mode operation for high efficiency over wide output current-load range.
