MP1470B High Efficiency, 2A, 16V, 500kHz Synchronous, Step-Down Converter in a 6-Pin TSOT23 EC EF N O E ER W M M TO DE EN S D M IG E PM N D S FO P2 R 33 2C The Future of Analog IC Technology DESCRIPTION FEATURES 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 protection and thermal shutdown. over-current The MP1470B requires a minimal number of readily available, standard, external components and is available in a compact 6-pin TSOT23 package.
