1 / 17 page MP1495S High Efficiency 3A, 16V, 500kHz Synchronous Step-Down Converter MP1495S Rev. 1.0 www.MonolithicPower.com 1 12/13/2013 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2013 MPS. All Rights Reserved. DESCRIPTION The MP1495S is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 3A continuous output current with excellent load and line regulation over a wide input supply range. The MP1495S 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 and thermal shut down. The MP1495S requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package. FEATURES Wide 4.5V-to-16V Operating Input Range 120mΩ/50mΩ Low R DS(ON) Internal Power MOSFETs High-Efficiency Synchronous Mode Operation Fixed 500kHz Switching Frequency Synchronizes to a 300kHz to 2MHz External Clock AAM Power-Save Mode Internal Soft-Start OCP Protection and Hiccup Thermal Shutdown Output Adjustable from 0.8V Available in an 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.
