After trying R-C snubber values combination, the 1000pF and 10R works the best. But still consuming 70mA at no load which is too much over the stated Vin operating current at 7mA. Theremust be a leaking at controller! Further, how an obtain Webench circuit simulation the I can verify the waveforms at various ciruit nodes?
Attached is the schematic of the circuit please help comment.
