Based on DC-DC converter type, the non-isolated (buck, boost, etc.) segment is estimated to hold the highest share of the market of 72.7% in 2025. This is attributed to their ability to efficiently regulate variable voltage requirements within vehicles.
Non-isolated converters are simpler in design, which helps reduce manufacturing costs compared to isolated converters. Their configurable nature allows them to step up or step-down voltages as needed to power different electrical components and systems inside modern automobiles.
Leading manufacturers of automotive DC-DC converters are constantly updating their non-isolated portfolios to meet growing end user demand as well as boost their sales. For instance, in October 2024, Vicor launched three new automotive-grade power modules, including the non-isolated PRM3735, aimed at 48 V zonal architectures from 800 V traction battery systems.
Based on end user, hybrid EV (PHEV & HEV) segment is projected to lead the industry, capturing 38.9% of the market share in 2025. This is mostly due to increases in hybrid electric vehicle production volumes.
Hybrid powertrains, which combine traditional internal combustion engines with electric motors and batteries, are seeing widespread adoption as an efficient stepping stone toward fully electric drivetrains. This transition is expected to boost sales of automotive DC-DC converters during the forthcoming period.

Hybrid powertrains, which combine traditional internal combustion engines with electric motors and batteries, are seeing widespread adoption as an efficient stepping stone toward fully electric drivetrains. This transition is expected to boost sales of automotive DC-DC converters during the forthcoming period.
In terms of system, 12 V system segment is slated to hold the highest market share of 35.9% in 2025. This is attributable to the immense proliferation of lower voltage ancillary electronics and driver-assistance features that rely on robust 12V power sourcing.
Despite rising 48V architectures, traditional 12V under-the-hood loads like lighting and basic comfort/convenience circuits remain the backbone of most vehicle electrical systems. Advanced driver-assistance systems, including infotainment, telematics, and active safety gear, constantly add more 12V loads.
Digital instrument clusters, connectivity suites, and an array of standard/optional comfort and convenience features all operate at lower voltages. As a result, the 12 V system category is expected to retain its market dominance in the coming years.

North America dominates the global automotive DC-DC converter industry. It will likely account for 33.7% of the global market share in 2025. This can be attributed to rising sales of electric vehicles and strong presence of leading automotive and technology companies in the region.
Rising adoption of autonomous and connected vehicles is boosting demand for automotive DC-DC converters. Similarly, government policies favoring new energy vehicles adoption are fueling automotive converter technology innovation.
North America is home to some of the leading automotive DC-DC converter companies. These players are constantly launching new solutions to meet evolving needs of the automotive industry. For instance, Eaton Corporation recently launched a new higher power version of its low-voltage 48-volt DC/DC converter for commercial and off-highway vehicles.
The new solution has the tendency to withstand harsh conditions (high ambient temperatures, vibration/shock). The move toward 48 V systems (dual voltage) supports the idea of rising adoption of electrified, connected vehicles in North America.
Asia Pacific remains at the epicentre of automotive DC-DC converter market growth. This is mostly due to increasing vehicle production and sales in major economies such as China and India.
Large automotive manufacturing hubs and trade relationships have accelerated proliferation of advanced automotive electronics. This is expected to create lucrative growth opportunities for automotive DC-DC converter manufacturers in the region during the forecast period.
The U.S. automotive DC-DC converter industry is growing steadily. This can be attributed to the shift toward vehicle electrification, ADAS integration, and improved power management requirements.
Automakers are adopting high-efficiency converters to support connected and hybrid powertrains. Leading companies such as Texas Instruments, Vicor, and Bel Power Solutions are introducing advanced, compact, and thermally efficient converter architectures suited for EV platforms.
China remains one of the fastest-growing markets for automotive DC-DC converters. This is mostly due to aggressive EV manufacturing policies, large-scale EV charging infrastructure, and strong domestic players.
Companies such as BYD, Huawei, and Contemporary Amperex Technology (CATL) are developing high-power, integrated DC-DC systems to enhance EV energy management. Likewise, government's push for NEVs continues to fuel demand for efficient power electronics across passenger and commercial EV segments.
Many international and regional companies are strengthening their presence in China through new facility expansions, mergers, agreements, contracts, and partnerships. For instance, in April 2025, Mahle secured a contract worth €200 million to supply DC‑DC converters for next‑generation battery electric vehicles in China.
