Hello, everyone,
I'm looking for someone experienced in designing SMPS's to provide a schematic for a simple yet reliable/robust circuit to be used in audio applications.It is essentially two power supplies that will be on one PCB, one that is +48V/1A (approximate current) and one that is +36V/500mA (also approximate current). Each voltage has to have a separate V- reference, hence two separate supplies. What I'm after is a bipolar +/-24V (+24, 0V, -24V) that has a minimum of 620mA per rail.
Normally I would figure this out on my own and ask questions along the way, but a potential client is wanting to purchase a prototype of mine and the time frame for building one is about one month. I have been using separate off the self PSUs but eventually I was going to need a single board PSU before I could release a commercial product if there was enough interest.
Ideally this would be taking two existing layouts for the different voltages and combining them. But since I do not have any layouts nor do I know enough about SMPS design to understand the various schematics found on the interwebs combined with the time factor I requiring myself to seek assistance. And this has to be solid without the need for testing or tweaking, so that also eliminates me from being the guy that designs the circuit.
I ultimately just need a schematic and a BOM. I have a local PCB layout guy that I use, but if you do already reliable layouts that can be combined as mentioned above then that would be helpful.
I do not know what this service would cost, so that would need to sorted upfront. Please email me at paul(at)scodovasound.com if you are experienced with SMPS design and if this would be of interest.
Thanks!
Paul
