Questions answered in these manuals
What is the function of the INHIBIT pin?
The INHIBIT pin acts as a Discontinuous Mode Detector that allows shut-off of the drive output by sensing the Synchronous Rectifier source-drain voltage.
How does the STSR3 synchronize its operation?
The STSR3 obtains synchronization directly from the secondary side using the voltage across the Synchronous mosfet as the information for the switching transitions.
