synchronous rectifier controller IC

Shindengen Electric Manufacturing Co. Ltd. (Japan) and SRMOS Inc. (Seattle, WA) recently announced what the companies claim is the world's first synchronous rectifier controller IC utilizing Prediction Technology. The MW Series is designed to simplify the control of synchronous rectifiers when they are used in switch mode power supplies (SMPS) to achieve higher overall conversion efficiencies. The MW Series is designed to overcome a number of problems that make synchronous rectifiers difficult to use in isolated power supplies. These problems include false/poor gate signals, reverse conduction, hot-swapping failures, poor light-load efficiency and N+1 redundant systems faults. According to the companies, the MW Series resolves virtually all of the problems associated with the implementation of synchronous rectification in power converters utilizing forward, flyback and half- or full-bridge topologies. The MW Series is capable of operating at switching frequencies up to 600KHz and can drive MOSFETs with Ciss up to 30nF. The MW models are available in either DIP-8 or SOP-8 packages.
