❯ 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.
├ Search symbols → TPS62160, 2.2µH inductor, 0603 MLCCs
├ Read datasheet → FB divider 523k / 100k
├ Seed schematic → my_board.kicad_sch + power rails
├ Place symbol → U1 TPS62160 · L1 2.2µH · C_in 22µF · C_out 2×22µF
└ Edit schematic → nets VIN, SW, FB, 3V3, GND
✗ ERC: U1 pin 5 (EN) left unconnected
├ Edit schematic → EN pulled to VIN via 100k
├ Check schematic → 0 introduced, 0 pre-existing
├ Review design → hot loop tight, FB clear of SW
├ Place board → 9 footprints on a 30×22mm outline
├ Route board → 31 tracks · 4 vias · 2 layers
├ Check board → 0 introduced, 0 pre-existing
└ Export fab → 16 file(s) in ./my_board/fab
