Examples of Technology Application ~Product Introduction~ DC-DC Converters Supporting High-Performance Electronics

Murata’s DC-DC converters are power conversion modules that convert input voltage into the optimal voltage according to the specifications of equipment and systems.
The lineup includes both isolated and non-isolated types, selected based on application requirements and design conditions.

The isolated type uses transformer-based isolation to provide electrical separation between input and output, ensuring high safety and strong noise immunity.
In contrast, the non-isolated type employs components optimized for target specifications, achieving high efficiency and fast transient response.

By comprehensively optimizing circuit design, magnetic design, and thermal design, Murata offers a broad lineup covering output currents from 1 A (ampere) to over 100 A.

In addition, by utilizing the latest power semiconductors and highly reliable components, Murata addresses diverse design requirements.

Murata’s DC-DC converters are characterized by their compact size, high efficiency, and high reliability.

For isolated DC-DC converters, technologies such as ferrite core design, PCB design, molding processes, and PCB embedding techniques deliver high insulation performance and reliability.
These products also comply with international standards such as IEEE and IEC, as well as industry standards such as DOSA.

For non-isolated types, proprietary circuit designs and heat dissipation structures achieve compact size, fast response, high efficiency, low noise, and high power density.
Improvements in inductor structures, end-face electrodes, and thermal designs contribute to higher electronic device performance, lower total cost, and improved productivity.

A key strength common to both types is product design that maximizes the performance of Murata’s own core components, including multilayer ceramic capacitors and inductors.
Through this approach, Murata meets a wide variety of customer needs.

Murata’s DC-DC converters have continuously evolved to meet changing market needs, with a focus on miniaturization, higher efficiency, and greater reliability.

In the past, performance was pursued within limited output power and size constraints.
Today, output power has been significantly increased while maintaining or even reducing product size.

This evolution has been driven by high-frequency switching technologies, the adoption of advanced power semiconductors, and proprietary design and manufacturing processes that enable higher power density and efficiency.

In addition, manufacturing technologies such as top-and-bottom board connection and fine-pitch mounting, together with design optimization simulations including thermal and electromagnetic field analysis, have greatly improved design flexibility and productivity.
In terms of reliability, Murata actively incorporates FMEA (Failure Mode and Effects Analysis), environmentally robust design, and margin design.
These efforts ensure stable quality and long service life even under harsh operating conditions.

Murata’s DC-DC converters are widely used in communication equipment, industrial equipment, medical devices, and home appliances.

Isolated DC-DC converters are primarily used in information and communication equipment such as servers, storage systems, and network switches, where safety and noise immunity are critical.
They are also applied in communication base stations, smart buildings, surveillance cameras, medical monitors, and robotics.

Non-isolated DC-DC converters are well suited for space-constrained, high-efficiency applications, particularly those using FPGAs (Field-Programmable Gate Arrays), such as PCI Express cards and accelerator cards.
They are also widely used in PLCs (Programmable Logic Controllers), HMIs (Human Machine Interfaces), motion control systems, LED (Light Emitting Diode) lighting, sensors, and video equipment.

Murata will continue to meet the diverse and evolving needs of society through its DC-DC converter technologies.
