Can the Silent Switchers be stacked for higher voltages? (I'm thinking of stacking 2 for 60V out). Thanks

 

[cabirio]

A quick question Jan: although this post refers to a specific card interface, I gather that it applies generally, i.e. the usual 100/100uF caps per PCB / group of opamps we use for LF supply bypassing must also go, no? One of the projects where I'm planning to use the SS would normally have three such pairs if I used an analog supply, how about replacing them with some 2u2 MLCC X7R I have?

Wow guys! That's awsone, that motivates me to go on with the project!

Question to you:

I was discussing with Martti the inclusion of a USB-C Pd option so that a Pd-enabled power bank can be used.
He is in favor - it will allow up to 15V input voltages and higher output currents.
Pd enabled power banks adapt the input power to what is 'requested' by the supply.
There are some additional parts and a very simple one-time configuration procedure I will have to do on a finished board.
The additional parts will increase the final price (not known yet) by about $ 10. Final price will creep up close to $ 100.
Do you believe this is worth it?

Hi Jan,
I have a phono project in mind that would require somewhere between 60 and 90 Volts. Just wondering if two or three Switchers could be stacked to provide that.
Thanks

 

[jan.didden]

In principle that would be possible but the SilentSwitcher is not isolated.
That means you would also have to stack input DC sources.

Maybe the diyaudio store high voltage supply is a better fit, they can be set from anywhere between 0 volts (less useful probably) to 500V output up to 400mA. Use two with a CT transformer to get +/-90V.

Jan

 

[Hearinspace]

OK, I'll check out your suggestion. Thanks !

 

[jan.didden]

😎

 

[lcsaszar]

Jan, would it be difficult to add -5 V (say @ 150 mA)? If it is, I can use a LDO regulator from -15 V. Just asking.

 

[jan.didden]

Yes that would be a majopr change/addition ;-)

Yes.

Best,

Yes. A welcome option. More than worth it.
