capacitor should be minimized. In addition, suffi cient copper
area should be provided at the anode and cathode terminals
of the diode for heat sinking. A larger area is preferred at the
quiet cathode terminal. A large anode area can increase high
frequency radiated EMI.
Quick Design Checklist
As with any power supply design, all LinkSwitch-XT designs
should be verifi ed on the bench to make sure that component
specifi cations are not exceeded under worst-case conditions. The
following minimum set of tests is strongly recommended:
1. Maximum drain voltage – Verify that V
2. Maximum drain current – At maximum ambient temperature,
650 V at the highest input voltage and peak (overload) output
power. The 50 V margin to the 700 V BV
gives margin for design variation, especially in Clampless
designs.

verify drain current waveforms for any signs of transformer

verify that the temperature specifi cations are not exceeded
for LinkSwitch-XT, transformer, output diode and output
capacitors. Enough thermal margin should be allowed for
part-to-part variation of the R
specifi ed in the data sheet. Under low line, maximum power,
a maximum LinkSwitch-XT SOURCE pin temperature of
105 °C is recommended to allow for these variations.
