Author: Karan Kumar Maheshwari Tool: KiCad 9.0 Controller IC: LM2596T-5 (Fixed 5V, TO-220-5) Board Size: 80.7mm × 34.1mm

A 5V regulated, thermally-protected DC-DC buck converter designed from scratch in KiCad. The design converts a 7–15V DC input to a stable regulated 5V output at up to 2A, featuring over-current protection (polyfuse), reverse-polarity protection, freewheeling diodes, a heatsink mount for the LM2596, and a power indicator LED.
