DC DC Converters

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.

2. Main Types and Functional Classification

Type	Functional Features	Application Examples
Non-Isolated Converters	Shared ground reference, high efficiency (85-95%), low cost	Point-of-load regulation in servers
Isolated Converters	Galvanic isolation (1-6kV), reinforced safety, wide input range	Medical equipment power supplies
Step-Down (Buck)	Converts higher input to lower output voltage	12V to 3.3V for microprocessors
Step-Up (Boost)	Increases input voltage to higher output levels	5V to 12V for display backlighting
Bidirectional	Supports power flow in both directions	Energy storage systems in EVs
