The increase in the adoption of electric vehicles contributed to the growth of the automotive DC-DC converter market. The output of the batteries in an electric vehicle is several hundred of volts but the components inside the vehicles require different voltages and most of the components run on lower voltage such as air-conditioning and in-built displays. The automotive DC-DC converter turns the high voltage into low voltage or low voltage to high. For instance, according to May 2022 published, Global EV Outlook 2022 report, electric vehicle (EV) sales had doubled from the previous year in 2021, reaching a new high of 6.6 million. Additionally, the sales of electric car vehicles worldwide in 2021 have reached 6600000 units from 2980000 units. The increase in the adoption of electric vehicles increases the demand for automotive DC-DC converters, driving the growth of the automotive DC-DC converter market.

The rising vehicle production is anticipated to drive the growth of the automotive DC-DC converter market in the coming years. Vehicle production encompasses the manufacturing, assembling, and construction of various types of vehicles, including automobiles, trucks, buses, motorcycles, and other motorized vehicles. Vehicles utilize automotive DC-DC converters to effectively regulate and convert electrical voltage, ensuring compatibility among different systems and components while optimizing power management for enhanced energy efficiency. For example, in May 2023, the European Automobile Manufacturers Association, a Belgium-based trade association, reported that approximately 85.4 million motor vehicles were produced globally in 2022, reflecting a 5.7% increase from 2021. Thus, the increase in vehicle production is propelling the growth of the automotive DC-DC converter market.

Prominent companies in the automotive DC-DC converter market are strategically focusing on product launches to meet the surging demand. These launches often involve introducing new lines of DC-DC converters designed to cater to specific needs. For example, in May 2022, Eaton Corporation, a leading US-based power management company, unveiled a new line of DC-DC converters tailored for 48-volt commercial vehicle architectures. These converters are meticulously crafted to address the unique power requirements of commercial vehicle electrical systems, ensuring efficient power conversion and management solutions. This strategic emphasis on product innovation aligns with the growing demand for automotive DC-DC converters in the market.

Automotive DC-DC converter manufacturers are increasingly focusing on the production of synchronous buck DC-DC converters. These converters are designed to generate a regulated voltage lower than their input voltage, efficiently delivering high currents while minimizing power loss. A notable example is ROHM, which introduced a series of automotive synchronous buck DC-DC converters characterized by reliability and low power consumption in a compact form. These converters find applications in critical systems such as radars, cameras, and sensors utilized in assisted driving.

In January 2023, Micross Components, a US-based provider specializing in high-reliability microelectronic components and services, completed the acquisition of the high-reliability (HiRel) DC-DC converter business from Infineon Technologies AG. The financial details of the acquisition remain undisclosed. This strategic move is poised to enhance Micross Components' capabilities in HiRel DC-DC converter power management solutions. Infineon Technologies AG, a Germany-based semiconductor company, previously operated in the HiRel DC-DC converter business, complementing its portfolio with hybrid and custom board-based power products.

Automotive DC-DC converters are electronic devices that transform direct current (DC) voltage from one level to another within vehicles. They play a crucial role in efficiently supplying power to various automotive systems, such as electric motors, infotainment systems, and battery management systems.

There are two main types of automotive DC-DC converters such as isolated and non-isolated. Isolated converters eliminate the DC path between input and output, while non-isolated converters maintain a direct connection between input and output. Various propulsion types, such as battery electric vehicles (BEV), fuel cell electric vehicles (FCEV), and plug-in hybrid vehicles (PHEV), utilize these converters. Input voltage ranges from < 40V, 40-70V, to >70V, and output voltage ranges from < 1kW, 1-10kW, 10-20kW, to >20kW. These converters find applications in both passenger vehicles and commercial vehicles.
