30 V 2 A Boost Converter
Budget: $30 – $250 CAD
I need a complete KiCad-based design for a DC-DC boost converter that takes a steady 20 V input from my wireless-charger receiver and delivers constant current constant voltage about 30V at 2Ato charge a 24 V battery pack. The current prototype idea uses a trim-pot for voltage adjustment, but I plan to swap that out for a digital potentiometer later, so please leave clean test points or pads for an easy drop-in replacement.
Key points you should factor in:
• Components: Keep the bill of materials limited to standard, readily available parts—no obscure custom silicon.
• Efficiency: Target the 85–95 % window; topology choice is up to you as long as it comfortably meets that range at 2 A full load.
• Built-in protection: incorporate over-current, over-voltage, and thermal shutdown so the battery and upstream wireless receiver stay safe.
• Layout: Space is not extremely tight, but I’ll eventually mount the board inside a small plastic enclosure with moderate airflow, so mind thermal paths and keep switching loops compact.
Deliverables I expect:
1. KiCad schematic (v7.x or newer) with clear net labels, reference designators, and manufacturer part numbers.
2. Two-layer (or more, if justified) KiCad PCB layout, ready for Gerber export.
3. Annotated BOM in CSV or XLSX, showing supplier links and pricing tiers when possible(JLC PCB preferable ).
4. Brief design notes covering efficiency calculations, chosen switching frequency, inductor and MOSFET sizing, plus guidance on where the digi-pot will plug in later.
5. Verification screenshots or data (LTspice, KiCad-Sim, or equivalent) that demonstrate the converter holding 30 V at 2 A with peak ripple, temperature rise, and overall efficiency clearly called out.
Once this module is proven I have several follow-on power designs waiting, so clean, well-documented work here can lead to more projects together. Let me know your expected timeline and any clarifying questions—looking forward to collaborating.
