Hello,
We are using UCC3808-2 for Generating 40V adjustable supply. Kindly find schematic in attachments.
We are providing Pulses as below :
1)"Dutycycle" = 100hz(10%,20%,50%,100%)
2)"PWR" = 100hz (0.1us increment)
3)IRF,VRF : 1MHZ
So at starting,when PWR = 0.1-0.5uS,The output waveform at TP4 is stable but with the Increment of PWR signal it is being distorted as shown below:
