Oops, so sorry to be so off base and off topic. I can only beg forgiveness for a 'senior moment'.

Your regulator modules are beautiful, as well as providing amazing performance. I am tempted to contemplate one for my Mac Mini server LPSU. But that should be in the 4A-6A range (through I measured only max 2.7A with cheap DMM). And I'm only a poor pensioner, so...

I will find a way to add heatsink to the little 1A modules. I am Not a circuit designer (nor trained in reading datasheets), but I've been building and repairing electronics since the early 1960's, so just another project challenge

Cheers, Dave A

I've got two LT3045's between LPS-1 and ultraRendu. 6V 1A is enough to power the ultraRendu. The LT3045's don't get hot. Not even warm.

Did you find the reason for the failure?

sq225917 is right, avoid that huge capacity at the output.

Wow, I thought the thickness might be to less for efficient cooling. Are you able to measure temperature?

Best regards

Finally got round to measuring temperature on the copper heat-sinks and after 4 hours running and enjoying the music, the heat-sinks were both between 40 & 43C which is excellent.

Will be ordering more for DAC and other possible improvements
