I am using UCC28700QDBVR-Q1 for designing four isolated output of 12 Vdc & 0.2 A each. Below are design goal parameters
Vin (min)= 250 Vdc
Vin (max)= 400 Vdc
Vout1, Vout2, Vout3, Vout4= 12 Vdc each
Iout1, Iout2, Iout3, Iout4= 0.2 A each (i.e total 0.8A)
Vbias= 12V & Ibias= 2.1 mA
I have calculated all the required parameters using IC datasheet. I have also calculated the turns ratio (Nps & Npa). But I couldn't able to calculate the number of turns at primary, secondary & auxiliary side.
Is there any reference document for the same?
