Anyone have some good places too learn about SMPSU design or can recommend a place that would do the heavy lifting of designing a SMPSU to set specs?

My first work effort involving a DC-DC switching PS was in the late 60's some 50 years ago...benb said:I remember using a LT1072 and reading "Switching Regulators for Poets" about 30 years ago. I think I was lucky in that these were some of the first all-in-one chips where the datasheet says use these resistors, these capacitors, this part # for the catch diode, this value and current rating inductor, and if your traces, especially the big current-carrying ones, are short and fat it'll work. Before then it was more of a black art.
For a new product design, one might be tempted to drop in a UL approved PS module to avoid that whole can of worms (dealing with mains voltages wrt UL approval).I'm not sure why you want to do this, it seems there are plenty off off-the-shelf SMPS modules around thesedays, not just from the power line, but for any x range of voltage input and y range of voltage output, and if they're from good manufacturers, they're speced for ripple voltage and stuff.

Yes there are some good off the shelf options if I have the space to accommodate them in a chassis. While I would like to go that route, there are some that do not provide me with the voltages I require.benb said:I'm not sure why you want to do this, it seems there are plenty off off-the-shelf SMPS modules around thesedays, not just from the power line, but for any x range of voltage input and y range of voltage output, and if they're from good manufacturers, they're speced for ripple voltage and stuff.
I would prefer a preassembled supply. I have some requirements that currently are not in the off the shelf options due to size or voltage or both.john12ax7 said:Mean well seems open to doing custom designs at reasonable volumes, there have been some threads on here about it.
Or do you want just a raw design that you would assemble yourself?

I've never used their products, but each time I get their info I am amazed at the degree of user-friendlyness their products seem to pack.
