2 00 ns to prevent premature termination of the on-cycle.
Verify that the leading edge current spike event is below
current limit at the end of the 200 ns blanking period.
3. Thermal check – At peak output power, minimum input
voltage and maximum ambient temperature, verify that the
temperature speci?cations are not exceeded for LinkSwitch ,
transformer, output diode and output capacitors. Enough
thermal margin should be allowed for part-to-part variation of
the R DS(ON) of LinkSwitch as speci?ed in the data sheet. Under
low line, peak power, a maximum LinkSwitch SOURCE pin
temperature of 100 °C is recommended to allow for these
variations.
4. Centered output characteristic – Using a transformer with
nominal primary inductance and at an input voltage midway
between low and high line, verify that the peak power point
occurs at the desired nominal output current, with the correct
output voltage. If this does not occur then the design should
be re?ned to ensure the overall tolerance limits are met.
