Digital Control:
The power supply output will be enabled when this signal is pulled low (< 0.8 V).
HIGH = Output V1 OFF
LOW = Output V1 ON
Active High signal asserted when the input voltage rises above the min input
voltage specified.
This signal is internally pulled up through 4.7 K ohms to the 3.3 V housekeeping
voltage.
Active High signal asserted when the output is within regulation. This signal is
internally pulled up through 1.0 K ohms to the 3.3 V housekeeping voltage.
This open collector signal generates two pulses per each fan revolution. This
signal is eternally pulled up to the housekeeping voltage.
This signal will cause the output to shut down when drive high (> 24 V) or left
floating. The PS_KILL will cause the output to latch off and requires recycle of
PS_ON or DC input to reset.
