(at 80% of IO, max; TA = 25
°C):
Case 1: On/Off Input Is Set for Unit On and then
Input Power Is Applied (delay from point at
which VI = 48 V until VO = 10% of VO, nom).
Case 2: 48 V Input Is Applied for at Least One
Second, and then the On/Off Input Is Set to
Turn the Module On (delay from point at which
on/off input is toggled until VO = 10% of
VO, nom).
Output Voltage Rise Time (time for VO to rise
from 10% of VO, nom to 90% of VO, nom)
Output Voltage Overshoot (at 80% of IO, max;
TA = 25
