ST AN1882 Application note Designing with the L6926 high efficiency monolithic synchronous step-down regulator
The L6926 is a high efficiency monolithic synchronous step-down regulator from STMicroelectronics. It integrates a high voltage MOSFET and a synchronous rectifier and can operate at 100% duty cycle, delivering up to 800mA of continuous output current and regulating the output voltage from 0.6V to VIN. This device is designed using BCDV technology and has a low quiescent current (25μA) and shutdown current (0.2μA), making it very suitable for battery-powered equipment such as PDAs, handheld terminals, DSCs (digital still cameras) and cell phones.

ST AN1645 Application note handbook
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...
