The idea is to also change the primary switcher output to keep dissipation and efficiency under control. So a total of 4 resistors have to be changed.
A friend of mine is going to put together a few prototypes from +/-5V to +/-24V so I can do some measurements.
I shipped a bunch of Silentswitchers yesterday to people who ordered and paid them; if you are one of them you should have received an email with the tracking number.

Hello Jan,
I just found your silentSwitcher when researching smps for audio. Performance of your design is very impressive and I'll be ordering one for my phono preamp for sure.
Have you written an article about the design of the regulator like for super regs? Is there a schematic available or you decided to keep it private?

I have run out of SilentSwitchers but the diyaudio store has some left. Grab them while they are there ;-)

Is there a source in the EU that has stock or will you be selling them directly again at some point in the future? I'm always happy not having to visit the customs office 😉
Jan, what’s the safest way to allow both USB and wall-wart usage, where both connections are brought outside the chassis? I would want to probably have some protection if both are plugged in. Just a mechanical switch?
Is the USB option only meant to be used with a USB charger? Can you still access the data lines? I'm interested in doing a USB powered DAC and using the +/-15V rails for the output buffer.
Sorry for late reaction. There is probably no risk for the SS as long as the max input voltage is observed. But the two sources may start to fight so yes keep them apart, a switch or a relay, also more fancy stuff like FET switches will work.
Jan
The data lines are not connected so you can use pass-through or whatever. They are not loaded by the SS.

Custom output SilentSwitcher
Just an update:
I just ordered a set of prototypes for the SilentSwitcher with customizeable outputs.
I will build up a set from +/-5 to +/-24, and characterize them with respect to output current and noise/ripple.
That'll take at least 6 weeks from now, but after that I will post the result and then will set up a Group Buy for the new sets.
thanks, Jan

Hi Jan,
Would it work if one would combine two SS-s so that the used voltages would be +/-15V and +48V.... that would mean tie up of the -24Vpin on one module with the GND on the other. But is that safe to do with these modules? If it is then a combo of old and new module would be a pretty cool supply for a good phantom powered mic preamp

When I am done characterizing the customizeable version I will probably do another group buy for those.
Jan
Good point. Yes the data lines are not used, they are not connected on the board. So you can still use them if you tap them off somewhere, at the board or if you have a USB connector on the back panel, you can route the two power lines to the SS and the data lines to wherever you want them.
Jan
It is safe to do for the modules if you supply each from a floating source. The two grounds of the two input supplies should not be connected.
How about using the + & -24 as if it were 0 & +48V? Would that work with the mic preamp?
Jan
I would buy one! The shipping cost at the DIYAudio store is so high ($28) that the total cost ends up at almost 1,5 times the original 69 Euro...
If a customizeable version will be made available how likely is it that you can keep the current size and mounting layout?
Finally! I am taking delivery of the customisable version next Monday!
As-delivered, the 'analog' output voltages are still +/-15V.
But! In the bag you will also find 3 sets of 4 resistors, which can be used to change the voltage to +/-12V, +/-8V or +/-5V, or any combination.
No need to remove any parts, just add a set of resistors. They are SMD but relatively large at 1206 size, so anybody should be able to solder those.
And to your specific question: they are still the same size boards, same mounting layout, no change in price!
See the attached as user guide for customization. I'll add more info as needed, and the basic info is still at The SilentSwitcher | Linear Audio NL .
I will start shipping next week, I have 100 boards available. But those who have indicated interest before are served first and I will contact them the next days.
