For Clampless designs, the Peak Drain Voltage is highly
dependent on Transformer capacitance and leakage
inductance. Please verify this on the bench and ensure that it
is below 650 V to allow 50 V margin for transformer variation.
Output Rectifier Maximum Peak Inverse Voltage
Recommended diode is 1N4003. Place diode on return leg of
bias winding for optimal EMI. See LinkSwitch-XT Design
