| Isolated DC-DC Convertors / Why more than one +Vin/-Vin? |
| (1/1) |
| john21443:
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: http://www.meanwellusa.com/productPdf.aspx?i=858#1 Page 4 contains the pin out. Thanks, John |

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, --- Quote ---DIP24 package with industry standard pinout --- End quote --- sums it up. |
