Logic Control
PS_ON/L
(Power supply enable)
The power supply output will be enabled when this signal is
pulled low (<0.8 V).
HIGH = Output V1 OFF
LOW = Output V1 ON
VIN_GOOD/H (Input OK)
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.
POK/H (Output OK)
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.
TACH_1
This open collector signal generates two pulses per each fan
revolution. This signal is eternally pulled up to the
housekeeping voltage.
PS_KILL
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.
