Smart Meters

Enabling robust AC/DC power supplies through PrimAccurate™ technology

Dialog's AccuSwitch™ and PrimAccurate™ technologies enable robust power supplies for Smart Meters that meet stringent global efficiency and no-load stand-by power consumption standards while offering a low BOM cost.

Digital power conversion up to 45W

Dialog’s PrimAccurate™ AC/DC converters and controllers are rugged and reliable, offering near-zero stand-by power consumption, efficiency greater than 85% and a high level of integration removing fragile opto-isolators and Y-caps. This technology uses proprietary digital algorithms that perform real-time waveform analysis to monitor the output voltage and current through an auxiliary winding on the main transformer instead of using direct feedback from the output voltage (isolated or non-isolated). Cycle-by-cycle analysis through Dialog's digital technology allows for tight load and line regulation to input and output changes and full protection without costly additional components such as power sense resistors.

Industrial Edge Computing

Our open-standard networking platforms and tools connect monitor and control devices in commercial and industrial IoT deployments. The new SmartServer IoT edge server platform enables companies to drive intelligent and automated decisions in the IIoT through its revolutionary open, extensible architecture that allows solutions to “Embrace” legacy devices and protocols, “Extend” with emerging IoT protocols and applications, and “Enhance” with insights from cloud and AI systems.

Custom ASICs & IP

Dialog (through its acquisition of Adesto) has many years’ experience in implementing full-custom industrial system-on-chip (SoC) designs, achieving as much as 80% bill of materials reductions for our customers. What’s more, because we optimize both at block and system level, our chips deliver the lowest total system power consumption and area, while delivering the best performance. Our integrated approach makes reverse engineering exceptionally impractical, thereby protecting your intellectual property.

Application-Specific Memories

Our non-volatile memory (NVM) devices are designed with specific features and embedded intelligence to dramatically reduce a system’s overall energy consumption and extend its battery life, while delivering higher performance, greater reliability, enhanced security, and lower system cost.

Communications Products

Our communications ICs are designed to enable reliable and easy communications for industrial devices and networks. Our highly programmable Power Line Communications (PLC) ICs enable OEMs to quickly develop robust and innovative solutions that meet the unique requirements of automotive applications, such as industrial-strength reliability and scalability.

For decades, our LonWorks platform has been powering train braking systems, and is the basis of several standards in in-train control. Our OFDM-class PLC modems provide unprecedented level of flexibility and noise immunity, and support communication standards for in-truck sensor communication, such as PLC4TRUCKS and G3-PLC, as well as uniquely robust proprietary modes used in battery chargers and battery management systems.

Dialog’s DiaSIM simulation models and tools enable simulation and validation of AC/DC power supplies using highly accurate models for selected products. All models and application circuits are available for download from the support website.
