STSR3 SYNCHRONOUS RECTIFIERS SMART DRIVER

STSR3 Smart Driver IC provides a high current outputs to properly drive secondary Power Mosfets used as Synchronous Rectifier in low output voltage, high efficiency Flyback Converters. From a synchronizing clock input, withdrawn on the secondary side of the isolation transformer, the IC generates a .

STSR3 Features

* xceeded an external diode (D2) connected to VCC must be added. The maximum negative voltage of

* 0.6V must be guaranteed for the Inhibit pin. If this negative voltage is exceeded the current must be limited to 50mA. If necessary, a diode (D1) connected to SGLGND can be added to satisfy this s
