Notes on ET Max:
1. ET Max is calculated to limit core loss and temperature rise at 200KHz based on a bipolar flux swing of 180mT Peak.
2. For Push-Pull topology, ET needs to be derated by 50% for the same flux swing when voltage is applied across half the primary winding turns.
3. Applied ET may need further derating for higher frequencies based on temperature rise from core and copper losses.
