Isolated DC-DC Convertors / Why more than one +Vin/-Vin?
« on: April 22, 2018, 04:16:01 pm »
I have noticed that with isolated DC DC converters that there tends to be duplicated input pins.   For example, 2 pins labeled as +Vin.  Is this just a convention?   Because higher amperage is required on the input side only?   Some other reason?

Here is an example:

Page 4 contains the pin out.

Thanks,

John

All depends on the maker, and the format of the converter. I've usually only seen multiple pins on the outputs. Usually to high of current for a single pin is the reason for multiple pins. Some standard formats have multiple input and output pins specified.

For the part you listed,

DIP24 package with industry standard pinout
sums it up.
