All your questions depend on the design of the unit. There are converter
units that must have a load, and others that can free run with no danger of
damage, or no shut down at all. Many of these units that are from
particular appliances and devices are designed to work with specific load
factors. There are many reasons why the engineers will choose to do so.

The universal type or general utility devices that are designed to stand
alone, are the ones that can usually be used with no specific load
specification. This would up to the rated maximum allowable load.

You would be best off to enquire to the manufacture for speciation and
application ratings for your device. Or, if you can have a detailed
schematic and have the knowledge base, you can trace out the circuits and
make the determination for yourself.

om...
To get a dual output DC-DC converter to start, do both outputs need to
have a load? If it does, both loads would use the common reference
'ground' correct?
I read the repair FAQ on SMPS testing, but didn't notice anything
about dual output converters. I just want to make sure I'm not going
to fry something by testing it wrong.

Thanks in advance.
