DC/DC Converters(FAQ)

A DC/DC converter is a device that accepts a DC input and produces a DC output. Usually, the input voltage is a range, for example 19-36Vdc on a “24Vdc” input. As long as the input voltage is within this range, you will receive a steady set output voltage.
 

The isolation refers to the connection between the input DC voltage and output DC voltage. On an isolated DC/DC converter the input and output are not directly connected.
 

A step-up DC/DC converter is a DC/DC converter that has an output that is a higher voltage than it’s input. A step-down DC/DC converter is a DC/DC converter that has an output that is a lower voltage than its output. Typically, we don’t refer to step-up or step-down on our website to avoid confusion with AC transformers.
 

Isolated DC/DC converters can be used to deliver a negative DC output.
