Many electronic circuits and gadgets like small DC motors, LED strips, sensors, and portable devices don't run directly on 12V. They need a lower voltage like 6V to work safely. If you only have a 12V battery or adapter, you can't connect it directly because it may damage the components. A DC‑DC 12V to 6V buck converter solves this problem by stepping down the voltage efficiently without wasting much power as heat.
One of the most popular ICs for this purpose is the MC34063A. With it, you can build a compact and reliable 6V, 1.5A non‑isolated step‑down power supply module for your projects.
