Digital Power Supplies.

Post by smile_man »

Do you peeps know anything about them?

I saw on the DBA custom page that Oliver had built himself a "digital power supply" and that is was far superior to analogue ones, no noise at all.

i understand not taking DBA too seriously, but im legit curious about digital power supplies, i'd never heard of them before.

and i mean to power the whole board, like a 1 spot or something, not having digital power inputs on pedlulz.

Godlyke actually makes a digital supply. It's like a 1 spot, but has twice the capacity.

What part of a power supply is digital? It's not the power itself.

Power filtering is yummy and means my pedlolz aren't noisy unless I want them to be. I've never seen digital power filtering.

Does anyone want to chime in? culturejam? that other guy who has the answers?

Now that's a thought! Your pedalboard would be the mat & could just charge all your pedals. The circuitry could just be built into the rest of the pedal, with no removable batteries or anything.

I'm working on and off on rechargeable pedals unsing lithium ion battery packs... haven't been able to figure out how to switch the charger. And all the 9V equivs are actually 7.4 volts... so it'd need a different sorta battery pack. Different battery pack would get a lot more juice out of a charge, though! (like, the equivalent of SEVERAL batteries).

It'd be easy to wire it up like a normal battery, and add a charge switch... hmmmz

Digital power supplies don't make sense to me, other than being more efficient (thus able to put out more power-- that Godlyke puts out twice what a 1-spot can).

this is something i have thought on as well. I think batteries are a real waste. embedding rechargables that are automatically recharge when your adapter is handy would be amazing. You could do it with a small MCU and the normal DC jack that picks battery or adapter depending on whats plugged in. You can have the same MCU manage a boost converter to get that 7.4 to 9v. Basically you need a small mcu a rechargeable cell and an inductor.

if you went tqfp you could probably fit it on a very small board.
