Dc-Dc Converter FAQ

1.  What is the difference between regulated and unregulated power supplies?

As the input voltage and load current are changed the output voltage will remain more constant with a regulated output power supply than with an unregulated output power supply. Learn more.

2.  What do the input ranges of 1:1, 2:1, 4:1, 8:1, and 12:1 on dc-dc converters mean?

Dc-dc converters do not have standardized input voltages as are commonly encountered with ac-dc supplies (120 V ~ 240 V) and so there is a desire to succinctly express the input voltage capability of the converters. The ratios (1:1, 2:1, etc.) are the ratio of minimum to maximum input voltage over which the converter will meet the data sheet specifications.

3.  Can a dc-dc converter convert a positive voltage to a negative voltage?

Yes, some of the CUI non-isolated and all of the CUI isolated converters can be used to create a negative output voltage from a positive input voltage. For non-isolated converters the application notes in the data sheet will indicate if the converter is capable of creating a negative output voltage. All isolated converters can have the positive output connected to ground and the negative output will then produce a negative voltage.
