Output Voltage Insights

The global market for DC-DC converters includes 3.3V, 5V, 12V, and 15V & above. The 5V section will likely grow at a CAGR of 12.2% and hold the largest market share over the forecast period. 5V DC-DC converters are specially made for distributed power supply systems where an isolated voltage is required. The market for DC-DC converters is presented with attractive potential by the rising demand for electric vehicles, the expanding medical sector, aircraft electrification, consumer electronics, and transportation. This voltage typically needs to be lowered to a lower intermediate bus voltage, specifically 5V or even lower, to power the system's support boards.

The 12V section will hold the second-largest market share. 12V DC-DC converters are frequently used in the automobile industry to connect the electric drive train components by increasing or decreasing voltage levels. DC-DC converters are required to control the power at the point of load in each device due to the growing number of control modules throughout the vehicle. They are crucial for voltage conversion and isolation.

Mounting Style Insights

By mounting style, the global market for DC-DC converters includes Surface-Mount and Through-Hole. The Through-Hole section will likely grow at a CAGR of 11.3% and hold the largest market share over the forecast period. A through-hole converter is often used to create an isolated, regulated, short circuit-protected output and is designed to run from an industry-standard 24V or 5V unregulated supply. These converters operate in the entire – 40°C to + 68°C temperature range, drive huge capacitive loads, and are suited for industrial applications.

The Surface-Mount section will hold the second-largest market share. Surface-mount components don't need mounting holes because they are mounted directly on the printed circuit board (PCB). The need for lighter and smaller components grows as technology develops. Thus, surface-mount technology (SMT), a new and enhanced technology, is produced.

Application Insights

The global market for DC-DC converter includes Smartphones, Servers & Storage, EV Battery Management units, Railways, Medical Equipment, and Others. The smartphone segment held the largest 42% share of the global market in 2024 and is projected to advance at a CAGR of 12% over the forecast period, driven by widespread use, reliance on battery power, and the critical need for efficient DC-DC converters to manage dynamic voltage and load requirements. Mobile devices primarily rely on a battery power supply, which varies daily depending on the device's use. Smartphones, tablets, and other mobile devices with NFC capabilities operate more efficiently, owing to DC-DC converters. Due to the unique requirements of a battery-operated system, such as an extensive input voltage range and dynamic operational load, developing a high-efficiency DC-DC converter for these devices is difficult.

The Medical Equipment section will hold the second-largest market share. The medical grade DC-DC converter series has > 8mm creepage and clearance distances, strengthened isolation with two patient protections, and minimal leakage. To meet the medical safety standard, these converters offer an additional level of safety above and beyond the usual functional isolation.
