Hi,
I am designing a DC-DC converter without Opto-coupler feedback. To achieve Isolation i am using UC2901 IC with 1:1 transformer instead of Opto-coupler. For reference attaching the rough circuit. I am facing a problem that at PIN 4 and PIN 5 of UC2901 no pulses are coming to drive transformer. Please let me know if anything wrong i did in the circuit.
Thanks & Regards,
