Isolated 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
