DESCRIPTION

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, STSR2P generates two driving signals with the self-setting of dead time between complementary pulses. The IC operation prevents secondary side shoot-through conditions providing proper timing at the outputs turn-off transition. This smart function operates through a fast cycle-after-cycle control logic mechanism based on an internal high frequency oscillator, synchronized by the clock signal.

■ SUPPLY VOLTAGE RANGE: 4.5V TO 5.5V

■ TYPICAL PEAK OUTPUT CURRENT: SOURCE -2A, SINK 3.5A

■ OPERATING FREQUENCY: 20 TO 750 KHZ

■ SMART TURN-OFF ANTICIPATION TIMING

■ OPERATION INDEPENDENT FROM THE FORWARD MAGNETIC RESET TECHNIQUE

■ POSSIBILITY TO OPERATE IN DISCONTINUOUS MODE
