DC-DC Converters

Isolated DC-DC converters convert a source of direct current (DC) from one voltage to another and contain an electrical barrier between the input and output to improve safety. They are suitable for a range of applications, including telecommunication equipment, industrial equipment, and consumer electronics.

RS Components offer a comprehensive selection of high-quality Converters from industry-leading brands including TDK-Lambda, XP Power, Murata Power Solutions, Recom, and many more.

What are they used for?

Isolated DC-DC converters are used within equipment and devices containing different circuits or sub-circuits where it is necessary to convert the voltage of a DC supply from one level to another. For converting AC to DC, an AC-DC converter would be used.

Types of isolated DC-DC converters

Isolated DC-DC converters come in a wide range of input and output voltages in both single outputs, dual outputs. We also offer medical and railway-approved converters for safety-critical applications.

Package or Module Types

Isolated DC-DC converters come in many shapes and packages to suit every eventuality. Some of the most popular are:

  • DIP16
  • DIP24
  • PDIP
  • SIP
  • Encapsulated
  • Full and half brick

Mounting Types

DC-DC converters are used in many different environments and applications so they need to be easy to mount or install. Our products come in a range of mounting options including:

  • Chassis mount
  • DIN-Rail mount
  • Flange mount
  • PCB mount
  • Rackmount
  • Surface mount
  • Through-hole

The advantages of isolated DC-DC converters

Meet international safety standards and regulations.
Electrical isolation provides additional safety to personnel in case of internal failure.
Wide range of voltage conversion with high efficiency.
Certain models are railway- and medical-approved.
