UCC28730: UCC28730

Part Number: UCC28730


Tool/software:

Hello all,

I am trying to simulate the mentioned Flyback controller in PSpice. But due to some unknown reasons, I am not getting the desired output.

I found the above circuit on TI's website and is the one I am using as a reference.

This circuit is the one I have designed in PSpice. When I simulate it, I am getting 19 nanovolts at the output. All pins except the HV pin are at ~0 volts. I checked the Gate-Source Voltage of the MOSFET as well, it is at ~0v too!

Can anybody please help?

Thank you!!
