PCB Design for Voltage Regulation
Updated project description
Updated to: "50 mm x 50 mm power-conversion board with a 3 V input and two separate regulated outputs: 5 V and 12 V. Each output is limited to 30 mA and includes the required boost-converter support components, decoupling, filtering, and output current-limiting stages. The design target includes schematic completion plus PCB/layout feasibility and manufacturability review."

I chose a 4-layer layout as the safer default for this power board: top and bottom for routing, one solid ground plane, and one internal power layer. That gives cleaner return paths and better noise control around the two switching regulators.

- Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portaljharwinbarrozo43.0M
- Wirelessly connects power nets on schematic. Identical to the net portal, but with a power symbol. Used to organize schematics and separate functional blocks. To wirelessly connect power net portals, give them the same designator. #portal #powerjharwinbarrozo11.4M
- A generic fixed resistor ideal for rapid circuit topology development. Its footprint automatically adapts based on the selected package case code—supporting 0402, 0603, 0805, 1203, and many other standard SMD packages, as well as axial horizontal and vertical configurations.
