Innovations in the field, such as Delta Electronics' B70SP series DC-DC converter for non-automotive applications, highlight the industry's response to growing demand. Introduced in November 2019, this product boasts 91.5% efficiency and is designed for various industrial and commercial electric-powered vehicles, including forklifts and electric motorcycles. Such advancements are expected to spur market growth in the near future.

The rise in EV adoption is another significant market driver. EVs require high-voltage DC battery systems, with many components needing lower voltage levels. DC-DC converters facilitate this by efficiently converting high-voltage DC from the battery to the required lower levels. Eaton Corporation's eMobility business, for example, secured a contract in November 2021 to supply a 24-to-12-volt DC-DC converter for a commercial heavy-duty BEV, showcasing the crucial role of these converters in EV functionality.

Isolated DC-DC converters, which accounted for 73.1% of the market share in 2022, are expected to maintain dominance. Their ability to provide electrical isolation between input and output circuits ensures safety, noise reduction, and effective handling of different ground potentials. This makes them indispensable across various applications, including data centers, which increasingly demand efficient power management solutions for high-performance computing equipment.

Regionally, Asia Pacific leads the market, driven by robust growth in consumer electronics, automotive sectors, and a strong presence of major electronic component manufacturers. North America follows, bolstered by the adoption of electric mobility, 5G network deployment, and stringent energy regulations.
