Power OK The POK pin of CN3 shall change from STATE (<400mV) to the high STATE (>4.5V) 100-500 ms after the main outputs are within the regulation limits. Conversely, the POK should be de-asserted to a low srare when any of the main output voltages fall below its under-voltage threshold, or when the main power has been removed for a time sufficiently long such that the power supply operation cannot be guaranteed beyond the power-down warning time. The power down warning time must be 1mS minimum. The electrical characteristics for the Power OK output driver are shown below.
