Board Dimensions

DC-DC Buck Converter Breakout is a type of electronic device that converts a higher voltage DC input to a lower voltage DC output. It uses a switching circuit to regulate the voltage and current output and improve the overall efficiency of the system. The Buck Converter is called so because it reduces (buckles) the input voltage. The term "Breakout" refers to a breakout board that contains the DC-DC Buck Converter chip and other necessary components such as capacitors, resistors, and inductors. The breakout board is designed to be easy to use, with screw terminals or headers for convenient connection to other electronic components. DC-DC Buck Converter Breakouts are commonly used in various applications, such as robotics, portable devices, battery-powered systems, and LED lighting. They are an essential part of many electronic devices, providing reliable and efficient voltage conversion to power the system.
