1. Overview

Board Mount DC-DC Converters are electronic devices that convert direct current (DC) from one voltage level to another through switching technology. They enable voltage regulation and power distribution in embedded systems, providing galvanic isolation, voltage matching, and efficiency optimization. These converters are critical in modern electronics for enabling compact designs, improving energy efficiency, and ensuring stable power delivery in applications ranging from consumer devices to industrial equipment.
