The following minimum set of tests is strongly recommended:
1. Maximum drain voltage – Verify that peak V
2. Maximum drain current – At maximum ambient temperature,

680 V at highest input voltage and maximum output power.
maximum input voltage and maximum output load, verify
drain current waveforms at start-up for any signs of trans-
former saturation and excessive leading edge current spikes.
LinkSwitch-CV has a leading edge blanking time of 215 ns to
prevent premature termination of the ON-cycle. Verify that
the leading edge current spike is below the allowed current
limit envelope for the drain current waveform at the end of
the 215 ns blanking period.

for LinkSwitch-CV, transformer, output diodes and output
capacitors. Enough thermal margin should be allowed for
the part-to-part variation of the R

maximum source pin temperature does not exceed 110 °C.
