MP6302DD-LF-Z

MP1474S High-Efficiency, 2A, 16V, 500kHz Synchronous, Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP1474S is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a compact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input-supply range. The MP1474S has synchronous-mode operation for higher efficiency over the output current-load range. • • Current-mode operation provides fast, transient response and eases loop stabilization. Full protection features include over-current protection (OCP) and thermal shutdown (TSD). The MP1474S requires a minimal number of readily available, standard, external components and is available in a space-saving 8-pin TSOT23 package. • • • • • • • • • • Wide 4.5V to 16V Operating-Input Range 150mΩ/70mΩ Low RDS(ON) Internal Power MOSFETs High-Efficiency Synchronous-Mode Operation Fixed 500kHz Switching Frequency Synchronizes from a 300kHz to 2MHz External Clock Power-Save Mode at Light Load Internal Soft-Start Power Good Indicator Over-Current Protection and Hiccup Thermal Shutdown Output Adjustable from 0.8V Available in a 8-pin TSOT-23 Package APPLICATIONS • • • • Notebook Systems and I/O Power Digital Set-Top Boxes Flat-Panel Television and Monitors Distributed Power Systems All MPS parts are lead-free and adhere to the RoHS directive.
