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)
TACH_1
PS_KILL
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.
