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

TypeFunctional FeaturesApplication Examples
Non-Isolated ConvertersShared ground reference, high efficiency (85-95%), low costPoint-of-load regulation in servers
Isolated ConvertersGalvanic isolation (1-6kV), reinforced safety, wide input rangeMedical equipment power supplies
Step-Down (Buck)Converts higher input to lower output voltage12V to 3.3V for microprocessors
Step-Up (Boost)Increases input voltage to higher output levels5V to 12V for display backlighting
BidirectionalSupports power flow in both directionsEnergy storage systems in EVs

3. Structure and Components

Typical construction includes:

  • Input EMI filter (common-mode choke + capacitors)
  • Power MOSFET/IGBT switching stage
  • Planar transformer (for isolation types)
  • PWM controller IC with feedback loop
  • Synchronous rectifier (for high-efficiency designs)
  • Output LC filter (inductor + ceramic capacitors)

4. Key Technical Specifications
