DC-DC Converter

We as an innovation leader for Power Semiconductor and Energy Efficiency technologies are continually developing and working on the best solutions for your applications. We are creating new system architectures using state-of-the-art IC and power semiconductors. As a DC-DC converter manufacturer, switch mode power supply (SMPS) has been our business for decades, including the fine regulation of direct current, also known as DC-DC (or DC to DC) conversion. In the area of DC-DC power supply we offer different DC-DC converters and solutions.



DC-DC-Converter (Automotive)

In the area of DC to DC converter (automotive) we offer several switch-mode power supplies (SMPS) for ECUs in automotive applications like body, safety and power train. Within our portfolio you can find single-rail supplies with various features and current capability for step-up (Boost) and step-down (Buck) architectures. In addition, system supplies with integrated pre-/post-regulator concept (DC to DC converters cascaded with linear regulators and trackers) are available to supply 32-bit microcontroller.

 

DC-DC-Converters (Industrial)

Our industrial DC-DC converters fitting a broad range of consumer, computing, communications and industrial applications. By leveraging our long standing and market leading experience in automotive power supplies application, we are expanding our DC-DC portfolio to provide supply solutions to our customer’s current and future application needs. Our high-efficiency switching DC-DC converters help to reduce energy consumption, extending operating time of battery powered systems and by this minimize costs of all kind of systems in operation.
