Hi all and happy new year,

I would want to build a high current PSU with the LT3046 (around 6A) does anybody have already did it ?

Best and thanks by advance

ADI North America will be on winter shutdown starting December 25, 2023; perhaps another community member can assist you until our return on January 8, 2024.

Thank you for the wishes and I hope the same for you.

The closest reference design to your requirement is the "LT3041 with four LDOs in parallel" reference design. I show that reference design from the datasheet in the image below. I also uploaded a bom, schematic, gerbers and layer pdfs if you would like to copy the "LT3041 with four LDOs in parallel" design. Just add two more LT3041s to get 6A output capability.

HI Arad and many thanks for your reply, and happy new year.

The problem is that I have to use the LT3046 and especially this !

Is there is a possibility to ad transistor for higher current ?

Thanks to you

Dave
