3.4.4 Dynamic load response
Test Conditions:
• The adapter is subjected to a load change from 0.33 % to 100 % at a slew rate of
1 A / ms
• The frequency of change is set to give the best readability of the deviation and setting
time
Remark: The voltage is measured at the end of the output cable, the minimum output
current of 15 mA prevents switching in to Standby mode.
Criteria to pass:
The output is not allowed to have an overshoot or undershoot beyond the specified limits
(+1 V to 0.5 V) after a load change.
