Hi Ti ,
I have some questions for you about UCC2897 when turn off transient .
1. I measure the AUX pin duty value about 100ns ,the duty almost > 95% it will excess the setting(86%)?( Ron/Roff setting : Ron=130kohm , Roff=18kohm , Tsw =5.133us , Ton/(Ton+Toff) = 0.8681 )
2. And why the clamp MOSFET have abnormal VDS waveform i would like to ask you if you have any idea.
3.The active clamp forward max duty have limit under the UCC2897 ?
*clamp mos vgs have inverse circuit form aux pin
thanks,
JJ
