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 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.
