Case 1: On/Off input is set to Logic Low (Module
ON) and then input power is applied (delay from
instant at which VIN =VIN, min until Vo=10% of Vo,set)
Case 2: Input power is applied for at least one second
and then the On/Off input is set to logic Low (delay from
instant at which Von/Off=0.3V until Vo=10% of Vo, set)
