SilentSwitcher - mains-free +/-15V and 6/5/3.3V power

[pgour]

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?

Jan

Yes, please.

A noob question: Would the PCB be assembled or would we have to assemble it?

The previous runs of SilentSwitcher were sold assembled. It’s all tight SMD componentry and would be very challenging to solder by hand. I can only assume this will be no different, but @jan.didden can definitively answer.

Thanks.

It will be fully assembled ready to rock.
There are some jumpers for output options, and for an ON/OFF switch.
No soldering required, except when you want to customize the output voltage, then you need to swap some resistors.
I'm waiting for the prototypes from Martti to test.

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?

Sorry Jan, I think my question above fell between the cracks, could you please clarify this? Many thanks in advance!
Cheers,
Cabirio

 

[jan.didden]

Sorry I missed that post. When using the SS you can leave in place any decoupling already on the board.
When you build ground up I would still use some 100nF decoupling locally near opamps and stuff, as these can be important for stability.
But you wouldn't need the large 100uF+ caps.
