UCC28950: UCC28950

Said Karasoy

Part Number: UCC28950

Hi,

I am trying to design smps by using your intagrated circuit which is ucc28950. It will be 1 kw. Input voltage is 310 vdc and output voltage is 59 vdc. By using your excell equations, I calculated my components value and I redesigned again your evaluation board about ucc28950. (600w Vin : 410Vdc Vout : 12Vdc) But despite everything I tried, I could not change the output voltage from 12v in pspice simulation. Can you help me about this ? I can send the calculations and and design file.

Thanks
