Hello, I want to convert 3.3V(Input) to 5V (Output). but my need separated ground for input and output … Please suggest.
Unfortunately we do not have anything in stock that will do this.
Below is a link to non-stocking numbers you can look at.
Welcome to the DigiKey Forum.
There are a few DC-to-DC converter modules that may meet your needs.
Be sure to verify your needs against the datasheet specification.
Based on your requirement for “separated ground”, it sounds like you are looking for an isolated voltage converter. Is that correct?
A few additional questions:
- Are you looking for a power supply, or just something to do isolated level translation?
If looking for isolated level translation, then you probably could use one of the following to give you an isolated link and then, presuming you have dedicated power supplies at both 3.3V and 5V already, the output will be shifted to the proper level.
If looking for a power supply:
- How much current do you need to provide on your 5V output?
- Does the output need to be tightly regulated (say within 5% regardless of load current)?
Here’s a link to some board-level isolated DC-DC converters which are capable of providing a 5V power supply with a 3.3V input.
