PS_INHIBIT – (pin B4)
DS1200-3 Series
Page 28
This signal pin should be grounded in the system. If left open, power supply operation will be inhibited
(StandBy V
output will remain on).
SB
SDA, SCL and S_INT – (pin C1, C2, D3)
Please refer to “Communication Bus Descriptions” section.
POWER GOOD– (pin C3)
The POWER GOOD is an output signal driven high, by the power supply to indicate that all outputs are valid. If any of the
power supply outputs fails below its regulation limits, this output will be driven low. The output signal is an open drain
output internally pulled up in the power supply to internal standby supply (anode side of StandBy Output or’ing circuit) via a
1K ohm resistor. It is capable of driving the output below 0.4V with a load of 4mA.
A0, A1 – (pins D1, D2)
Please refer to “Communication Bus Descriptions” section.
StandBy Remote Sense – (pin D4)
The StandBy Output of the DS1200-3 is also equipped with a Remote Sensing capability that will compensate upto 50mV
of voltage drop for the positive rail. The StandBy Output Remote Sense pin should be connected as close to the load as
possible, or connected to the StandBy Output pins at the base of the output connector if not used. If left open, the remote
sense might not work properly and the voltage level of StandBy Output can be lower than the guaranteed spec.
