This repository contains the hardware design files for a compact, high-efficiency DC-DC step-down (buck) converter based on the LGS5145 integrated circuit.
This PCB is designed to take a wide input voltage (4.5V to 55V) and convert it to a stable, lower output voltage with a continuous current capacity of up to 1.0A. The 1.2MHz switching frequency allows for the use of small, low-profile external components. Its wide input range makes it suitable for demanding applications, including 42V automotive power systems.
