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.
