Hello, I have a strange problem with the driver, I used UCC21732 with desat protection and secondary side supply provided by Murata DC-DC converter with +20/-5V and the +20V is adjusted to +18V using LM2941. The circuit is as follows when I power up the driver it consumes a lot of currents and the output of LM2941 shows 4.7V, and the primary side of the UCC21732 driver supply starts rising to 7V.
DO you have any idea why I am seeing this problem with the UCC21732 driver?
