Product overview

Description

STSR30 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 From a synchronizing clock input, withdrawn on the secondary side of the isolation transformer, the IC generates a driving signal with set dead times with respect to the primary side PWM signal.

The IC operation prevents secondary side shoot-through conditions at turn-on of the primary switch providing anticipation in turn-off the output. This smart function is implemented by a fast cycle-after-cycle logic control mechanism, based on a high frequency oscillator synchronized by the clock signal. This anticipation is externally set through external component. A special Inhibit function, detecting the voltage across the Synchronous FET, allows to shut-off the drive output during discontinuous mode condition. A Disable pin allows turning off the device during no-load condition reducing overall current consumption.
