Set the output at maximum loading. Decrease the input voltage with 5VAC step. Verify
the FB voltage is under overload state (between 2.7~4V). Measure the maximum duty
and waveform.
Set the output at the maximum load. Remove power.
Set the output at maximum loading. Heat the IC with a heatgun, measure the waveform to
enable the OTP, and disable the OTP.
