MP1470GJ-Z

MP1470 High-Efficiency, 2A, 16V, 500kHz Synchronous, Step-Down Converter In a 6-Pin TSOT 23 The Future of Analog IC Technology DESCRIPTION FEATURES The MP1470 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 MP1470 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 MP1470 requires a minimal number of readily-available, standard, external components and is available in a space-saving 6-pin TSOT23 package. • • • • • • • • • Wide 4.7V-to-16V Operating Input Range 163mΩ/86mΩ Low-RDS(ON) Internal Power MOSFETs Proprietary Switching-Loss–Reduction Technique High-Efficiency Synchronous-Mode Operation Fixed 500kHz Switching Frequency Internal AAM Power-Save Mode for High Efficiency at Light Load Internal Soft-Start Over-Current Protection and Hiccup Thermal Shutdown Output Adjustable from 0.8V Available in a 6-pin TSOT-23 package APPLICATIONS • • • • Game Consoles Digital Set-Top Boxes Flat-Panel Television and Monitors General Purposes All MPS parts are lead-free and adhere to the RoHS directive.
