TOP270EG OutPut Voltage High Issue
I have designed SMPS for 77-143V DC input to 32V,2.7Amp output with the help of Pi Software tool.
But,after simulation and all real world output voltage is coming around 44V at no load.Putting load it is 0V output. Device is restarting again and again, Control Pin voltage 5.8v to 4.8V fluctuation. Schematic is attached for you reference. Please, guide me and try to find out the issue.
Input Voltage: 77-143V DC (110V DC Nominal Input).
Output: 32V, 2,7Amp Peak Current ( 1Amp Nominal Current continuous).
