Output Diode
For best performance, the area of the loop connecting the
secondary winding, the output diode and the output fi lter
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-LP 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
650 V at the highest input voltage and peak (overload) output
power. A 50 V margin to the 700 V BV
margin for design variation, especially in Clampless designs.

temperature, verify that the temperature specifi cations
are not exceeded for LinkSwitch-LP, transformer, output
diode and output capacitors. Enough thermal margin
should be allowed for part-to-part variation of the R
LinkSwitch-LP as specifi ed in the data sheet. Under low line
and maximum power, a maximum LinkSwitch-LP SOURCE pin
temperature of 100 °C is recommended to allow for
these variations.
