This document is the product manual of STSR30 synchronous rectifier smart driver. The driver adopts SO-8 package, the working voltage range is 4V-5.5V, the typical peak output current is 1.5A, the operating frequency is 20 to 500KHz, and it can automatically turn off the output with a duty cycle less than 14%. It can also operate in discontinuous mode.
The IC provides two complementary high current outputs to drive Power Mosfets. The IC is dedicated to properly drive secondary Synchronous Rectifiers medium power, low output voltage, high efficiency in 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. A fixed anticipation in turning-off the OUTGATE1 with respect to the clock signal transition is provided, while the anticipation in turning off the OUTGATE2 can be set through external components. The adopted transitions revelation mechanism makes circuit operation independent by the forward magnetic reset technique used, avoiding most of the common problems inherent in self-driven synchronous rectifiers. A special Inhibit function allows the shut-off of OUTGATE2. This feature makes discontinuous conduction mode possible.

The L5973AD is a step down monolithic power switching regulator with a switch current limit of 2 A, so it is able to deliver more than 1.5 A DC current to the load depending on the application conditions. The output voltage can be set from 1.235 V to 35 V. The high current level is also achieved thanks to an SO8 package with exposed frame, that allows to reduce the RthJA down to approximately 40 °C/W. The device uses an internal P-Channel D-MOS transistor (with a typical of 200 mΩ) as switching element to avoid the use of bootstrap capacitor and guarantee high efficiency. An internal oscillator fixes the switching frequency at 500 kHz to minimize the size of external components. Having a minimum input voltage of 4 V
