Dear TI Experts
I have doubt on the self synchronous rectification stage used in the PMP5711.
In one of the TI document (http://www.ti.com/lit/an/slua535/slua535.pdf) it has been told that If the input voltage range is wider than two to one, self driven synchronous rectification may not be an option and a control driven solution should instead be considered. But, in this case the range for Gate to source voltage is going higher than the 20V. Then For this zener diode has been used.
I am making Active Clamp Forward Converter with Synchronous Rectification for the Input range of 16V to 50V and Output is 5V, 30A. Can I use the same self synchronous rectification circuit which is used in PMP5711. My target efficiency is above 90% at 50% to 100% load.
Thanks & Regards
