Hello,
I am trying to design a converter that the input is 300-400V and the output is 28V/35A. It can be 500W converter and it can be used parallel using syncronous pins of the IC.
Firstly I am trying to desing it by simulation (TINA).I am calculating all the values of passive elements by using excel document and using them in simulation. I cannot regulate the output voltage using TINA. I could not understand which pin of the UCC28950 is used for the output voltage feedback. Do you have any available simulations for these desings:
1-input:300-400V and the output: 28V/35A (It can be 500W converter and it can be used parallel using syncronous pins of the IC)
2-input:18-36V and the output: 28V/35A (It can be 500W converter and it can be used parallel using syncronous pins of the IC)
