This paper describes the functionality and the operation of the STSR2P device used as the secondary synchronous rectifier driver in Forward topology switched mode power supplies. The STSR2P Smart Driver IC provides two complementary high current outputs to drive Power Mosfets. The IC is dedicated to properly drive secondary Synchronous Rectifiers in medium power, low output voltage, high efficiency Forward Converters. From a synchronizing clock input, the IC generates two driving signals with a certain dead time between complementary pulses. The adopted transitions...
