MP1470B
Active
2A, 16V, 500kHz, Synchronous Step-Down Converter with forced CCM
Product Description
The MP1470B is 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 synchronous mode 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 compact 6-pin TSOT23 package.
