Hey mravlca,
Im trying to understand power supplies and am interested in building one as a project and im sure a question like this could have many answers but what makes your pcb a "low noise power supply." As well how might it compare to other power supplies which seem to use far more components and are more expensive. Im interested in a low noise somewhat hi quality power supply but i guess what im getting at is, if you were to tell me one power supply which cost $30 to build was 99.9% as good as one which cost $125, well i would say the .01% loss in quality is acceptable. On the other hand if it was only 80% as good as the more expensive power supply i might feel spending the extra money was worth it. Im looking at building a power supply in lieu of a cheap SMPS im currently using so looking for an upgrade and not just to build something comparable to my SMPS. Note i make no judgements about your pcb, in fact i really like how simple and straightforward it seems, but im interested in whether your aim was simplicity over absolute quality or quality and simplicity.
I belive that linear regulator is better than SMPS, atleast for lower voltages and currents (=< 30V, 5A). This PCB was built for quality and simplicity so that it can be used anywhere, but you must know that this is not one of the best regulators out there but it is pretty good and very versatile.
I am using it for my TPA3106 amplifier, which has better sound stage and bass punch comparing to SMPS, also my headphone amp has it.
Hello,
do you offer any discount for larger quantity like the previous GB you linked to? 10pc,25pc,50pc etc?
Thank`s
Gisle
Yes I can offer such discount. 1.5€/pcs for more than 10pcs and 1.2€/pcs for more than 25pcs.
Best Regards,
Ales
Hello,
I`ll take 25pc if you still have boards left.
Shipping to Norway
Thank`s
Gisle
Hi Gisle,
Sorry, no more boards left, but I plan to order some more really soon.
Best Regards,
Ales
Hi Ales,
Do you have more boards for purchase? I'm most interested in your TPS7A project but will buy some of these if available. Thanks. Regards.
Hi!
Yes I have boards available but they are in white colour, blacks are out of stock again. I will also have TPS7A4700 boards ready soon, probably by the end of next week.
Best Regards,
Ales
I'm interested in 4 boards, not sure on differences between board colours? No preference if layout is identical.
Thanks
Hi,
layout is identical, only difference is in the colour of the PCB.
BR,
Ales
