Hi,
I am Trying to make one DC to Dc convertor with UCC35706, strangely all the four devices I had is gone bad ie PIN 3 Vff shows zero Volt.
The schmatic design is taken from another working design. Its resonant single switch forward convertor.
Please help me to acertain if the device has gone bad or not.
Is the devics very sensitive to ESD,ie can my handly counld have spoiled the IC
Thanks,
Sunil
