About this Gig
Automotive electronics demand robust power supplies. Converting noisy 12V/24V battery systems into stable 5V, 3.3V, or higher voltages requires heavy copper traces, proper ground management, and strategic thermal dissipation.
I'm an expert in high current automotive power electronics layouts, including DC-DC buck/boost converters, MOSFET switches, relay driver boards, and power distribution modules (PDMs).
What you will get;
Trace copper weight optimization 1oz / 2oz copper specs
Thermal via arrays and heatsink copper pouring
Low EMI PCB layout with short switching loops
Reverse voltage and TVS load dump protection
Gerber, NC Drill, and complete fabrication package
BOM with active LCSC/DigiKey part numbers
Pick & Place CPL files for JLCPCB manufacturing
Software; KiCad, EasyEDA, Altium.
High current generates heatI calculate copper width according to IPC-2221 standards so your board runs cool under load without blowing traces.
Send me your voltage inputs, target output current, and board dimensions, and lets design a rock solid power board for your build!
FAQ
How do you ensure the PCB traces don't melt under 10A, 20A, or higher currents?
I run IPC-2221 trace width calculations based on your target amperage and allowable temperature rise. For heavy currents, I utilize 2oz copper thickness, wide polygon pours, thermal via arrays, or exposed trace areas
Can you design custom power distribution modules (PDMs) with solid-state MOSFET switching?
Yes. I design solid-state relay (SSR) circuits using high-side automotive MOSFET drivers (BTS/PROFET series) with built-in overcurrent protection to replace mechanical relays and fuses.
Will you select components that are active and currently in stock at suppliers?
Yes. I cross-reference all parts directly against live stock at major distributors like LCSC, DigiKey, and Mouser to ensure you don't receive a design with backordered components.
Can you include status LEDs or fuse protection for every output rail?
Absolutely. I routinely integrate blade fuse footprints (mini/ATO), PTC resettable fuses, and diagnostic indicator LEDs so you can immediately see which output rail is active or tripped.
Can this power board be manufactured completely by SMT assembly houses like JLCPCB?
Yes! I match surface-mount components (inductors, capacitors, ICs, SMD fuses) directly with JLCPCB/PCBWay standard parts libraries to keep automated assembly fast and cost-effective.
