PIN DESCRIPTION
INPUT PINS
EMI. This pin can be used for additional and
1 improved EMI Filtration. Connect this pin
only to EMO pin using safety capacitor.
2
VIN+. This pin connects to the positive (+)
output of the input bridge rectifiers
3
VIN-. This pin connects to the negative (-)
output of the input bridge.
4
ATD. AT Detect Pin. Please see section F.
5.
RSD. This pin can be used for remotely
5 shutting down the module from the target
device. Please see section F.6.
6 NC
7 CPR. Remote Shut down Pin.
OUTPUT PINS
+VDC. This pin provides the regulated
8 output from the DC/DC converter.
(Internally connected to pin 9).
.+VDC. This pin provides the regulated
9 output from the DC/DC converter.
(Internally connected to pin 8).
EMO. This pin can be used for additional
10 and improved EMI Filtration. Connect this
pin only to EMI pin using safety capacitor
OADJ. The output voltage can be adjusted
11 from its nominal value. Please see section
F.8.
12
-VDC. The ground return for the +VDC
output. (Internally connected to pin 13).
13
-VDC. The ground return for the +VDC
output. (Internally connected to pin 12).
To maintain isolation integrity, always
connect respective input and output poles
only via X or Y safety capacitor. Maintain
isolation barrier on motherboard PCB as per
physical package.
