3.2.1.3 Full load efficiency PFC plus flyback stage
Test conditions:
Before any measurements were recorded, the adapter is set to maximum load and is
preheated till the readings were stabilized.
Remark: The output voltage is measured at the end of the output cable. (2 × 20 mΩ)
Criteria to pass:
The efficiency (η) must be > 88 % at the maximum continuous output load.

3.3 Timing and protection
3.3.1 Switch-on delay and output rise time
Test conditions:
The electronic load is set to Constant Current (CC) mode and Von = 0 V. The electronic
load is set to the maximum continuous output current.
Criteria to pass:
Switch-on delay: two seconds maximum after the AC mains voltage is applied to the
time when the output is within regulation
Output rise time: The output voltage must rise from 10 % of the maximum to the
regulation limit within 30 ms. There must be a smooth and continuous ramp-up of the
output voltage. No voltage with a negative polarity must be present at the output
during start-up
No output bounce or hiccup is allowed during switch-on.
There be must be sufficient margin between the FBCTRL signal and the 4.5 V
time-out trigger level to avoid false triggering of the time-out protection due to
component tolerances
