Isolated DC/DC Converters

RECOM is one of the world’s most experienced DC/DC converter manufacturers, dating back to its founding in 1975. Thus, it is not surprising that our DC/DC module portfolio is the most extensive on the market with a wide variety of sizes, pinning options, operating temperature ranges and input/output voltage combinations, starting at a quarter of a watt and going up to 3kW.

We offer non-isolated DC/DC converters with efficiencies over 97% through to 20 kVDC isolated DC/DC converters, from sub-miniature SMD mount modules up to half-brick power converters and operating temperatures down to -40°C and up to +100°C, all with international safety certifications and detailed technical datasheets that are readily available on our site. The ‘E’ versions of our most popular converters are cost-optimized options suitable for high-volume, extremely price-sensitive applications.

We believe that we have the most reliable, energy-saving, and high-performance DC/DC converters available on the market and that somewhere in our wide portfolio is an ideal fit for your application needs. If not, as one of the most innovative manufacturers in the business, we release on average a new DC/DC module every month.

It's not all too long ago that a transformer, rectifier and linear regulator was the main technology in power conversion – nowadays the DC/DC converter gradually replaces the linear regulator and the primary-side switching controller is replacing the simple 50Hz mains transformer. The immense technical progress of new circuits, components, and materials has made it possible to increase the performance and to improve the thermal behavior, while simultaneously substantially reducing the size, weight and cost of power supplies. Consequently, switching regulators are used today in large numbers and are the standard technology in DC/DC power conversion. Modern DC/DC converters are designed to provide efficient power conversion to deliver a controlled, safe, and stable DC power supply for a variety of electronic instruments, devices and systems.

Modular DC/DC converters were always considered to be more expensive than discrete solutions. However, with the commissioning of its own SMT factory, we are able to offer selected converter series at very attractive prices. With economies of scale, we realize with our cost-effective power supplies cost savings of up to 50% compared to similar products without compromising quality. It is not only the design engineer that wins by using our products, but also the buyer as procurement begins and ends with just one single module. No more specifying and sourcing of multiple components.

Unexpected problems such as component tolerances, testing failures and EMC issues coming from discrete designs can lead to significant delays and re-design costs. The planned launch of a product can quickly be delayed by months. Tested and certified DC/DC converters not only save on development time but also reduce the risk of time-to-market delays and simplify the final certification process.


By simply adding a few components to the DC/DC converter, its EMC compliance can reach EN55022, Class A or Class B.


Standard case sizes, footprints and pinouts guarantee straightforward integration into your design.

Whether regulated or unregulated, isolated to 10kVDC, or carefully designed for extremely high ambient temperatures of +100°C – we offer a suitable modular DC/DC converter for every application. Unregulated DC/DC converters are typically used in general purpose power isolation and voltage matching applications and feature a full industrial operating temperature range of -40°C up to +85°C without derating. Regulated DC/DC converters are designed for industrial applications, can drive high capacitive loads and operate over a broad temperature range without derating. Furthermore, they provide stable output voltages when the input voltage suddenly changes.
