A control circuit (20) having a slow-start section (29) is enabled to carry out its expected, principal function(2) only after the voltage at the slow-start section input has reached a certain level. The system assures that a delay interval in control circuit operation is measured from the time that devices (212,213) within the circuit's internal voltage supply (22) become effective to deliver voltage levels sufficient to allow the circuit (20) to perform the principal function. A delay network (50A) is connected across a device (212) of the internal voltage supply (22), which otherwise supplies an operating voltage level to the control circuit (20). |
