AC/DC Embedded

Reducing the number of external components

Digital controllers with integrated power devices to provide a high reliability AC/DC power supply through technology that allows fewer external components.

Digital Power Conversion up to 45W

Our AC/DC converter products offer both stand-alone digital controllers and digital controllers for embedded systems incorporate PrimAccurate™ and AccuSwitch™ technologies, reducing the number of external components, including the opto-isolator, which is the weak link in harsh environments, characteristic of embedded applications. Dialog's digital control cores further improve performance by reducing EMI, improving power efficiency by reducing no load power consumption to virtually zero and enhancing load and line regulation using real-time waveform analysis.
