Part Number: UCC28710
Tool/software: TINA-TI or Spice Models
I built a AC/DC 5V/2A flyback circuit with UCC28710 transient model, and its schematic is to duplicateevaluation board PMP9202 with simplified components in the input and output.
Some diodes and the primary side HV-MOS model was collected and put in the simulation.
But the simulation result shows the primary side HV-MOS could not be switched continuously that no output was found.
Attached are the result and TINA .TSC file, could anyone help take a look on this simulation ? I appreciate if there is any comment on this.
I downloaded the TINA model from web and modified it to make it like your application test bench. It runs fine with all the extra components and value changes you had. I am attaching the modified circuit here, with screen shoot of UCC28710_PMP9202.tscwaveform
