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.
