#0101PowerDesignedv1.1

Buck converter 3.3 V / 5 V, 2 A, Vin up to 17 V (TPS562203)

TI TPS562203 synchronous buck, 4.5–17 V input, 2 A, 4.7 µH shielded inductor. Input: R6 (0R) is fitted by default; D1 (B130 Schottky, DNP) can be fitted instead for reverse-polarity protection; ferrite bead FB2. Enable: R4 (0R to VIN, always on) or R5 (to BUCK_EN). Test points on input and output.

FAQ

Which KiCad version do I need?

KiCad 10. The files are saved in the KiCad 10 format and are meant to be placed with KiCad’s Design Blocks feature (schematic block, then “Apply Design Block Layout” on the PCB).

Do I need the Circuit Issues part library?

No. Symbols are embedded in the schematic and footprints in the PCB, so the block opens on its own. Parts carry manufacturer part numbers and LCSC codes.

Is the layout production-ready?

Not yet. The PCB part is a layout fragment without a board outline and its DRC clean-up is still open. The status above shows where this block is.

Can I use the template in a commercial product?

The licence terms are published together with the first release.
