1 / 19 page MP2234S High-Efficiency, 2A, 16V, 800kHz Synchronous, Step-Down Converter MP2234S Rev.1.0 www.MonolithicPower.com 1 4/3/2015 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2015 MPS. All Rights Reserved. The Future of Analog IC Technology DESCRIPTION The MP2234S 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 MP2234S 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 shut down (TSD). The MP2234S 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 • 140mΩ/60mΩ Low RDS(ON) Internal Power MOSFETs • High-Efficiency Synchronous Mode Operation • Fixed 800kHz Switching Frequency • Synchronizes from a 300kHz-to-2MHz External Clock • Power-Save Mode at Light Load • External Soft-Start • Over Current Protection and Hiccup • Thermal Shutdown • Output Adjustable from 0.804V • 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, halogen free, and adhere to the RoHS directive.
