      @rozpruwacz said in 3.3v Boost Converter with Pass-Through: Hi, I just came across this project and I like the idea of pass trough very much I have a question, why did You use the LTC3525D part instead of MCP1640C which You already used in other boost converter projects ? MCP1640C is 5 times cheaper than LTC3525D and they are quite similar. I just now revised the board to expose the Enable pin, so now you can do a pass-through if you wish. I also made it more compact and gave it a ground-plane on the back. https://www.openhardware.io/view/279 Enjoy!

      Right you are. Live and learn (even at 81), and I even learned a new word -'vias.' Thanks.

      @alexsh1 If the pinout is the same, then the PCB should work.

      @Marcel-StΓΆr Sorry, I don't know. Maybe try the datasheet.
