Analog Devices présente les plus petits convertisseurs de courant cc vers cc isolés de l'industrie

Analog Devices, Inc. (ADI), un leader mondial dans les semi-conducteurs haute performance pour les applications de traitement de signaux et une pionnière en technologie d'isolateurs numériques, a présenté aujourd'hui les plus petits convertisseurs de courant cc vers cc isolés de l'industrie. L'ADuM5010, l'ADuM6010, l'ADuM521x et l'ADuM621x font appel à la technologie propriétaire de convertisseurs de courant cc vers cc isolés isoPower® d'ADI pour fournir 150 mW de puissance de sortie tout en occupant moins d'espace que les solutions concurrentes basées sur module. L'ADuM521x et l'ADuM621x intègrent également deux voies de la technologie primée d'isolation de données iCoupler® d'ADI pour réduire jusqu'à 75 pour cent de l'espace de carte par rapport aux alternatives basées sur optocoupleur. Les convertisseurs étendent le portefeuille de courant isolé d'ADI en fournissant aux concepteurs une approche compacte, rentable et simple à mettre en œuvre pour répondre aux exigences en termes de courant et de données isolés. La combinaison de taille et de puissance de sortie permet également de résoudre les contraintes croissantes d'espace et de puissance dont les ingénieurs doivent tenir compte lors de la conception de systèmes de contrôle, d'équipements d'essais et de mesures, d'alimentation électrique, de pilotes de moteurs et d'autres applications industrielles et d'instrumentation.

« Cette nouvelle ligne de convertisseurs de courant cc vers cc isoPower offre un excellent compromis entre la puissance et la taille, permettant aux clients de concevoir plus de fonctionnalités et d'efficacité dans des formats plus compacts tout en continuant de minimiser le coût des systèmes », a déclaré David Krakauer, directeur de ligne des produits isolateurs numériques iCoupler chez Analog Devices. « Avec son approche collaborative, son assistance à la conception et ses connaissances au niveau des systèmes, ADI aide nos clients à profiter pleinement de notre technologie d'isolation de courant ».

L'ensemble des nouveaux convertisseurs cc vers cc fournissent une puissance régulée et isolée, réglable de 3,15 V à 5,25 V. L'ADuM5010 et l'ADuM521x sont certifiés pour une isolation d'une valeur effective de 2,5 kV (1 minute), tandis que l'ADuM6010 et l'ADuM621x sont certifiés pour une isolation d'une valeur effective de 3,75 kV (1 minute) avec d'autres certifications pour une isolation renforcée conforme à la norme VDE 0884-10. En incorporant la technologie d'isolateur numérique iCoupler d'ADI, l'ADuM521x et l'ADuM621x réduisent le nombre de composants et simplifient et améliorent la vitesse, la fiabilité et l'efficacité de conception en éliminant la nécessité d'optocoupleurs. Les versions à quatre voies de ces produits à l'aide de la technologie isoPower plus compacte et rentable d'ADI seront lancées prochainement.

Les convertisseurs de courant cc vers cc isolés réduisent les délais de développement de systèmes

Analog Devices pré-certifie ses modules de convertisseurs pour aider les concepteurs à réduire les délais de développement de systèmes, contrairement à des convertisseurs de courant cc vers cc discrets à composants multiples qui imposent aux concepteurs d'entreprendre le processus coûteux et laborieux de certification individuelle d'une douzaine de pièces, voire plus. En outre, les modules de convertisseurs de courant cc vers cc isolés d'ADI ne nécessitent pas d'ajout de composants en dehors de deux condensateurs de découplage, facilitant ainsi la complexité de conception et réduisant les délais de mise sur le marché.

Principales caractéristiques des convertisseurs de courant cc vers cc isolés ADuM5010/ADuM6010 et ADuM521x/ADuM621x

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
The Internet of Things is in the early stages of mainstream deployment but it promises to unlock value and rapidly transform how organizations manage, operationalize, and monetize their assets. IoT is a complex structure of hardware, sensors, applications, analytics and devices that need to be able to communicate geographically and across all functions. Once the data is collected from numerous endpoints, the challenge then becomes converting it into actionable insight.
Consumer IoT applications provide data about the user that just doesn’t exist in traditional PC or mobile web applications. This rich data, or “context,” enables the highly personalized consumer experiences that characterize many consumer IoT apps. This same data is also providing brands with unprecedented insight into how their connected products are being used, while, at the same time, powering highly targeted engagement and marketing opportunities. In his session at @ThingsExpo, Nathan Treloar, President and COO of Bebaio, will explore examples of brands transforming their businesses by t...
With the Apple Watch making its way onto wrists all over the world, it’s only a matter of time before it becomes a staple in the workplace. In fact, Forrester reported that 68 percent of technology and business decision-makers characterize wearables as a top priority for 2015. Recognizing their business value early on, FinancialForce.com was the first to bring ERP to wearables, helping streamline communication across front and back office functions. In his session at @ThingsExpo, Kevin Roberts, GM of Platform at FinancialForce.com, will discuss the value of business applications on wearable ...
While many app developers are comfortable building apps for the smartphone, there is a whole new world out there. In his session at @ThingsExpo, Narayan Sainaney, Co-founder and CTO of Mojio, will discuss how the business case for connected car apps is growing and, with open platform companies having already done the heavy lifting, there really is no barrier to entry.
With the proliferation of connected devices underpinning new Internet of Things systems, Brandon Schulz, Director of Luxoft IoT – Retail, will be looking at the transformation of the retail customer experience in brick and mortar stores in his session at @ThingsExpo. Questions he will address include: Will beacons drop to the wayside like QR codes, or be a proximity-based profit driver? How will the customer experience change in stores of all types when everything can be instrumented and analyzed? As an area of investment, how might a retail company move towards an innovation methodolo...
The Internet of Things (IoT) is about the digitization of physical assets including sensors, devices, machines, gateways, and the network. It creates possibilities for significant value creation and new revenue generating business models via data democratization and ubiquitous analytics across IoT networks. The explosion of data in all forms in IoT requires a more robust and broader lens in order to enable smarter timely actions and better outcomes. Business operations become the key driver of IoT applications and projects. Business operations, IT, and data scientists need advanced analytics t...
Contrary to mainstream media attention, the multiple possibilities of how consumer IoT will transform our everyday lives aren’t the only angle of this headline-gaining trend. There’s a huge opportunity for “industrial IoT” and “Smart Cities” to impact the world in the same capacity – especially during critical situations. For example, a community water dam that needs to release water can leverage embedded critical communications logic to alert the appropriate individuals, on the right device, as soon as they are needed to take action.
