UCC2803: Flyback AC/DC converter, Tina-Ti

Part Number: UCC2803
Other Parts Discussed in Thread: TINA-TI


I am designing an AC/DC converter of 60 W, 19 V output but after simulation in Tina-TI using UCC2803, the pwm controller is turning on, but not getting output voltage. What to do? 

Attaching circuit design of Webench, my own simulation, and its waveform.

Please Reply
