Monolithic Power Systems MP1470B | Demoboard EV1470B-J-00B

Description

The EV1470B-J-00B Evaluation Board is designed to demonstrate the capabilities of MPS’ MP1470B, A high-frequency, synchronous rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current over a wide input supply range, with excellent load and line regulation. The MP1470B has synchronousmode operation for higher efficiency over the output current-load range.Current-mode operation provides fast transient response and eases loop stabilization. Protection features include over-current protection and thermal shutdown.The MP1470B requires a minimal number of readily-available, standard, external components and is available in a space-saving 6-pin TSOT23 package.
