MP9942GJ Datasheet | Monolithic Power Systems

DESCRIPTION The MP9942 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very pact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input supply range. The MP9942 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 shutdown. The MP9942 requires a minimal number of readily-available standard external ponents, and is available in a space-saving 8-pin TSOT23 package. TYPICAL APPLICATION MP9942 High Efficiency 2A, 36V, 410k Hz Synchronous Step-Down Converter with Power Good FEATURES - Wide 4V to 36V Continuous Operating Input Range - 90mΩ/55mΩ Low RDS(ON) Internal Power MOSFETs - High-Efficiency Synchronous Mode Operation - 410k Hz Switching Frequency - Synchronizes from 200k Hz to 2.2MHz External Clock - High Duty Cycle for Automotive Cold-crank - Internal Power-Save Mode - Internal Soft-Start - Power Good Indicator - Over-Current Protection with Hiccup - Thermal Shutdown - Output Adjustable from 0.8V - Available in an 8-pin TSOT-23 package APPLICATIONS - Automotive - Industrial Control System - Distributed Power Systems All MPS parts are lead-free and adhere to the Ro HS directive.
