Do you want to avoid failures and reduce the number of variants? One converter. Many platforms. Full power.
Standard converters often cover only a limited input voltage range, lose performance at high temperatures or require additional protective measures. Demke DC/DC converters are designed for real-world industrial conditions – not just ideal datasheet values.
One DC/DC converter for multiple platforms
Up to 1:10 wide input range – for systems from 12 V lead-acid to 160 V lithium.
Fewer variants. Less effort in development and purchasing.
Full power even at extreme temperatures
Up to 1200 W at ambient temperatures from −40 °C to +85 °C. No thermal power derating, no oversizing required.
Built for harsh industrial environments
Full PU potting in an aluminium housing. Up to IP69K: resistant to vibration, moisture and dirt across the entire portfolio.
Maximum efficiency for mobile systems
Up to 99% efficiency means less heat and longer battery runtime.
100% tested before delivery
Every DC/DC converter undergoes multiple fully automated tests during production before leaving the factory.
MTBF – designed for maximum service life
We place the highest value on quality – including when selecting components. With an MTBF (mean time between failures) of up to 1.5 million hours, our DC/DC converters are designed for high reliability and maximum service life.
The diversity of our DC/DC converters and custom solutions
Robust and durable DC/DC converters with output power from 1 W to 1200 W – galvanically isolated, functionally isolated or non-isolated, with ultra-wide input voltage ranges for industrial applications. Find the right DC/DC converter for your requirements or develop a custom solution together with us.
DC/DC Buck Converters
Our non-isolated DC/DC step-down converters efficiently reduce higher input voltages to stable output voltages. With power ratings up to 1,200 W, ultra-wide input voltage ranges, CC/CV control and robust full PU potting, they are ideal for vehicles, machinery and industrial onboard power systems – without power derating.
DC/DC buck-boost converters
DC/DC buck-boost converters stabilize the supply voltage even when the input voltage is above or below the desired output voltage. The compact buck-boost converters with CC/CV control are particularly suitable for battery systems, supercapacitors, automated guided vehicles (AGVs) and mobile systems.
Isolated DC/DC buck-boost converters
Our galvanically isolated DC/DC converters provide stable output voltages and ensure reliable electrical isolation between input and output. With power ratings up to 800 W, wide input voltage ranges, CC/CV control and an EMC-optimized design, they are ideal for demanding industrial and vehicle applications.
Isolated DC/DC Converters for THT PCB Mounting
Compact, galvanically isolated DC/DC converters for direct THT mounting on PCBs. With power ratings from 3 W to 30 W, a 4:1 wide input voltage range and a robust aluminium housing, they are ideal for industrial electronics, railway technology, e-mobility and automotive applications.
Custom DC/DC converters
Is a standard device not enough? We adapt the input voltage, output voltage, power, CC/CV control characteristics, connections and mechanical design to your application – from a modified standard product to a fully custom development.

FAQs
Have questions? We have answers!
What Is a DC/DC Converter?
A DC/DC converter converts one DC voltage into another and provides connected loads with a stable supply voltage. Depending on the topology, the input voltage can be stepped down, stepped up or stabilized even when the input voltage fluctuates significantly. DC/DC converters are used in battery systems, vehicles, machinery, robotics and industrial applications, among others.
How can a DC/DC converter be customized?
Demke DC/DC converters can be adapted to different technical requirements depending on the application. Possible modifications include the input voltage range, output voltage, power, control characteristics, connections, housing and mechanical design. The scope ranges from a modified standard product to a fully custom development.
