💡 Product Overview

A Buck Converter, also known as a step-down converter, is a type of Switched-Mode Power Supply (SMPS). Its core function is to convert a higher DC input voltage into a lower, stable, and controllable DC output voltage. It is significantly more efficient than traditional linear regulators and is essential for modern electronic devices.
