Turn-on Delay and Rise Times
(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 °C)
