SYNCHRONOUS RECTIFIER  
SMART DRIVER FOR FLYBACK  
SUPPLY VOLTAGE RANGE: 4V TO 5.5V  
TYPICAL PEAK OUTPUT CURRENT:  
(SOURCE-SINK: 1.5A)  
OPERATING FREQUENCY: 20 TO 500 KHz  
INHIBIT BLANKING TIME: 700 ns  
AUTOMATIC TURN OFF FOR DUTY-CYCLE  
LESS THAN 14%  
POSSIBILITY TO OPERATE IN  
DISCONTINUOUS MODE  
SO-8  
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.  
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withdrawn on the secondary side of the isolation  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
