CUI's Novum Power Modules use Powervation Digital Controllers
Powervation Ltd. announced that power supply and power module maker CUI Inc. has selected its PV3012 next-generation digital controller in two newly-released power product families, the NDM2P series and the NSM2P series. Both product families are point-of-load (POL) dc-dc converters.

The new NDM2P-series PMBus-compliant POL converters are the latest additions to the company's Novum Advanced Power product line. Also new is the Novum NSM2P-series, the industry's first self-compensating no-bus digital POL DC/DC module family, which targets customers who need the flexibility and configurability of digital power, as well as low component count and high reliability, but who do not wish to include digital bus communications in their systems.
Both power module product families deliver intelligent adaptive self-compensation through the use of Powervation's Auto-Control® technology. Automatically and dynamically balancing the trade-off between performance and system stability in real time, Auto-Control compensates for changes in the converter's output impedance (e.g., component aging, manufacturing variances, and temperature) and wide variety of potential loads.

In addition to providing the company's patented adaptive loop compensation technology, the PV3012's differential measurement and high resolution ADC, enables precision measurement and precision control of outputs. PV3012 provides 0.5% set-point voltage regulation over the module's wide input range of 4.5 V ~ 14 V, and output current measurement down to 3% accuracy over a wide range of load currents. The converter's output can be configured and controlled through pre-stored configurations, single resistor pin strapping, or via PMBus commands. When used in dual phase mode, phases may be added or removed as the load varies, so that efficiency is maximized over the load range. Additionally, the outputs of the phases are interleaved so that the effective switching frequency at the output is doubled. With Powervation's Digital Stress Share (DSS) and PLL synchronization, multiple PV3012 devices may be used in parallel to increase the number of phases supporting the application's load.
Comments Mark Adams, Senior Vice President, CUI Inc.: "The configurability and flexibility of the PV3012 and its outstanding transient response, allows our modules the performance and features demanded by our customer base. The NDM2P modules are our highest performing modules in these key areas."
Opinion: Maximising Synergies between Power Electronics and ICT for improving Energy Efficiency
Adds Powervation's CEO, Mike McAuliffe: "CUI's innovative new power modules perfectly utilizes our adaptive digital controllers to maximize performance regardless of load or operating conditions. We are pleased to have worked closely with CUI on developing these new modules and are sure that customers will appreciate the significant performance benefits that they offer."

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
