of the diode for heatsinking. 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-HF designs
should be veri?ed on the bench to make sure that component
speci?cations are not exceeded under worst-case conditions. The
following minimum set of tests is strongly recommended:
1. Maximum drain voltage – Verify that V DS does not exceed
675 V at the highest input voltage and peak (overload) output
power.
2. Maximum drain current – At maximum ambient temperature,
maximum input voltage and peak output (overload) power,
verify drain current waveforms for any signs of transformer
saturation and excessive leading edge current spikes at
startup. Repeat under steady state conditions and verify that
the leading edge current spike event is below I LIMIT(MIN) at the
end of the t LEB(MIN) . Under all conditions, the maximum drain
current should be below the speci?ed absolute maximum
ratings.
3. Thermal Check – At speci?ed maximum output power,
minimum input voltage and maximum ambient temperature,
verify that the temperature speci?cations are not exceeded
for LinkSwitch-HF , transformer, output diode, and output
capacitors. Enough thermal margin should be allowed for
part-to-part variation of the R DS(ON) of LinkSwitch-HF as
speci?ed in the data sheet. Under low line, maximum power,
a maximum LinkSwitch-HF SOURCE pin temperature of
100 °C is recommended to allow for these variations.
