Description

The EV1470H-J-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP1470H, A high-frequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs. Itoffers a very compact solution to achieve a 2A continuous output current over a wide input supply range, with excellent load and line regulation. The MP1470H has synchronousmode operation for higher efficiency over theoutput current-load range. Current-mode operation provides fast transientresponse and eases loop stabilization. Protection features include over-current protection and thermal shutdown.The MP1470H requires a minimal number of readily-available, standard, external components and is available in a space-saving 6-pin TSOT23 package.
