❯ a 3.3V buck converter from 12V, 2A, on a 2-layer board
I'll seed the schematic, wire the power stage, then check, route and review the board.
• Searched
├ search symbols → TPS62160, 2.2µH inductor, 0603 MLCCs
└ read datasheet → FB divider 523k / 100k
• Seeded
└ seed schematic → my_board.kicad_sch + power rails
• Placed
└ place symbol → U1 TPS62160 · L1 2.2µH · C_in 22µF · C_out 2×22µF
• Updated
└ edit schematic → nets VIN, SW, FB, 3V3, GND
✗ ERC: U1 pin 5 (EN) left unconnected
• Updated
└ edit schematic → EN pulled to VIN via 100k
✓ ERC clean — 0 errors, 0 warnings
• Checked
└ review design → hot loop tight, FB clear of SW
• Placed
└ place board → 9 footprints on a 30×22mm outline
• Routed
└ route board → 31 tracks · 4 vias · 2 layers
• Checked
├ check board → DRC clean
└ review board → no visual defects
• Rendered
└ render board → board-top.png, board-bottom.png
• Exported
└ export fab → gerbers/my_board-v1.zip
─ Worked for 52s ────────────────────────────────
Done — schematic, routed board and fab package are in ./my_board. Open it in KiCad, or ask for changes.
