BYPASS pin voltage. The parameters I S2 and V BP are provided in
the parameter table of the LinkSwitch-II data sheet. Diode D6 can
be any low cost diode such as FR102, 1N4148 or BAV19/20/21.
Quick Design Checklist
As with any power supply design, all LinkSwitch-II designs
should be verified on the bench to make sure that component
specifications are not exceeded under worst-case conditions.
The following minimum set of tests is strongly recommended:
1. Maximum drain voltage – Verify that peak V DS does not exceed
680 V at the highest input voltage and maximum output power.
2. Maximum drain current – At maximum ambient temperature,
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-II has a leading edge blanking time of 170 ns to
prevent premature termination of the ON-cycle.
3. Thermal check – At maximum output power, both minimum
and maximum input voltage and maximum ambient tempera-
ture; verify that temperature specifications are not exceeded
for LinkSwitch-II, transformer, output diodes and output
capacitors. Enough thermal margin should be allowed for
part-to-part variation of the R DS(ON) of LinkSwitch-II, as specified
in the data sheet. To assure 10% CC tolerance a maximum
SOURCE pin temperature of 90 oC is recommended.
