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 allows to shut-off the drive output. This  
feature makes discontinuous conduction mode  
possible and avoids reverse conduction of the  
synchronous rectifier.  
DESCRIPTION  
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withdrawn on the secondary side of the isolation  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 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
