About this Gig
Professional Power Supply & PCB Layout Design (DC-DC, EV BMS, Solar, IoT)
Are you looking for a rock-solid, high-efficiency power supply design that won't blow up your prototype or fail EMI/EMC testing? You are in the right place.
I am a professional electronics engineer specializing in high-performance hardware and PCB layout design. Whether you are building a compact IoT smart device or a high-current EV Battery Management System (BMS), I design for reliability, thermal efficiency, and manufacturability (DFM).
️ What I Can Design For You:
- DC-DC Converters: Buck, Boost, Buck-Boost, SEPIC, and Isolated topologies.
- EV BMS: Balancing circuits, voltage/current sensing, and protection stages.
- Solar Power: MPPT charge controllers and battery storage integration.
- IoT & Smart Devices: Low-quiescent current, ultra-compact, and battery-optimized power paths
What You Get in the Final Delivery:
- Schematic Files (Altium, KiCad, or EasyEDA)
- PCB Layout
- Manufacturing Files
- Production Documents
- 3D STEP Model

FAQ
Which PCB design software do you use?
I primarily work in Altium Designer and KiCad, but I can also use EasyEDA if your project requires a web-based, rapid-prototyping workflow. Please specify your preference when ordering.
How do you handle thermal management for high-current EV BMS or DC-DC designs?
I use thick copper weights (2oz–3oz+ depending on your needs), extensive thermal via matrices to transfer heat to outer layers, dedicated copper pours, and optimal component spacing. If necessary, I can design the layout to accommodate heatsinks or thermal pads.
Will my design pass EMI/EMC certification?
Yes, I follow strict high-frequency and power layout rules: minimizing switching node loop areas, separating analog and digital grounds appropriately, placing decoupling capacitors as close to pins as possible, and using solid ground return paths to suppress noise.
Can you help me select the right components to avoid supply chain shortages?
Absolutely, When compiling your Bill of Materials (BOM), I prioritize components that have high stock levels at major distributors (DigiKey, Mouser, LCSC) and select pin-to-pin compatible alternatives where possible.
Do you source parts and manufacture the physical boards?
No, I provide the digital blueprints (Gerber, BOM, Pick & Place files) required for manufacturing. However, I ensure these files are 100% ready to drop directly into any fabrication house like JLCPCB, PCBWay, or advanced domestic manufacturers.
What do you need to start the project?
I need your schematic, project specifications, PCB dimensions, component preferences, and any reference files or requirements.
Can you design high-current power PCBs?
Yes, I specialize in high-current and power electronics PCB layouts with thermal and EMI optimization.
Can you help with prototype support?
Yes, I can support prototype testing and design improvements.
