1.2 Pin Description
Pin # | Name | Description |
1 |
+VDC | DC Output. This pin provides the regulated output from the DC/DC converter. |
2 | ||
3 | -VDC | DC Return. This pin is the return path for the +VDC output. |
4 |
ADJ | Output Adjust. The output voltage can be adjusted from is nominal value, by connecting an external resistor from this pin to either the +VDC pin or the -VDC pin. |
5 |
VIN+ | Direct Input +. This pin connects to the positive (+) output of the input bridge rectifiers. |
6 | ||
7 |
VIN- | Direct Input -. This pin connects to the negative (-) output of the input bridge rectifiers. |
