About this Gig
Does your audio, sensor or analog board pick up switching noise, or do you need several clean voltages from one input? I design low-noise and multi-rail power supply boards, laid out to keep noise out of the circuits that matter.
What I offer
Multi-rail design: 3.3V, 5V, 12V, split rails and more from one input
Low-noise design: switching stage plus LDO post-regulation and filtering
Power sequencing and rail protection where your design needs it
Schematic and PCB layout with careful grounding and a tight switching loop
Gerbers, BOM and assembly files for JLCPCB or PCBWay
Editable source files (KiCad, Altium or EasyEDA)
Why buyers choose me
Layout built to keep switching noise away from sensitive analog parts
Parts checked for stock, so no order-time surprises
I ask about your noise targets and loads before I design
Revisions included in every package
To start, send me
input voltage, the rails and currents you need, how sensitive your analog parts are (audio, ADC, sensor, RF), and board size limit.
Not sure how many rails you need? Message me and Ill help you map it out
FAQ
Can you power an audio or sensor board without switching noise?
Yes. I use a switching stage for efficiency, then LDO post-regulation and filtering for the sensitive rails, with layout to match.
How many rails can you design?
Up to 3 in the Standard package and more in Premium or a custom offer. Send your list and I’ll quote it.
Can you do positive and negative (split) rails
Yes, within low-voltage DC limits. Send the voltages and current needs
Will you guarantee a specific noise level?
I design for low noise and tell you what to expect, but actual noise depends on your whole board and must be measured on your bench. I don’t promise a figure I can’t verify.
Which files do I get?
Gerbers, BOM, assembly files and editable source files.
