Analog Devices präsentiert branchenweit kleinste DC-DC-Trennwandler

Analog Devices, Inc. (ADI), ein weltweit führender Anbieter leistungsstarker Halbleiter für Signalverarbeitungsanwendungen und Pionier auf dem Gebiet digitaler Isolationstechnologien, hat heute den branchenweit kleinsten DC-DC-Trennwandler vorgestellt. Die Varianten ADuM5010, ADuM6010, ADuM521x und ADuM621x verwenden ADIs patentgeschützte DC-DC-Trennwandler-Technologie mit isoPower®-Isolation für eine Ausgangsleistung von 150 mW und belegen weniger Platz auf der Leiterplatte als modulbasierte Konkurrenzlösungen. ADuM521x und ADuM621x verfügen außerdem über zwei Kanäle mit der preisgekrönten ADI-Datenisolationstechnologie iCoupler®, die den Platzbedarf im Vergleich zu Optokoppler-basierten Alternativen um weitere 75 Prozent reduziert. Die Trennwandler ergänzen das ADI-Portfolio isolierter Leistungskomponenten und bieten Elektronikingenieuren eine kompakte, leicht zu implementierende und kosteneffiziente Lösung für isolierte Leistungs- und Datenanforderungen. Ihre Abmessungen und Ausgangsleistung erfüllen die steigenden Anforderungen an Platzbedarf und Leistung, die Elektronikingenieure beim Entwurf von Steuersystemen, Prüf- und Messgeräten, Netzgeräten, Elektroantrieben und anderen industriellen Anwendungen und Instrumenten zu beachten haben.

„Diese neue Produktreihe von isoPower DC-DC-Wandlern bietet ein exzellentes Gleichgewicht von Leistung und Abmessungen und erlaubt unseren Kunden, mehr Funktionen und Effizienz in kleinere Formfaktoren zu packen und die Systemkosten dabei weiter zu senken“, erläutert David Krakauer, Product Line Manager, iCoupler Digital Isolator Products, Analog Devices. „Der kooperationsorientierte Ansatz, die Entwicklungs-Supportleistungen und Systemkenntnisse von ADI helfen unseren Kunden, die Vorteile unserer Isolationstechnologie in vollem Umfang auszuschöpfen.“

Alle neuen DC-DC-Trennwandler bieten eine geregelte Isolationsspannung von 3,15 V bis 5,25 V. ADuM5010 und ADuM521x wurden für eine Isolationsspannung von 2,5 kV rms (1 Min.) zertifiziert. ADuM6010 und ADuM621x wurden für eine Isolationsspannung von 3,75 kV rms (1 Min.) sowie eine verstärkte Isolation gemäß VDE 0884-10 zertifiziert. Durch die Integration der digitalen Isolationstechnologie iCoupler von ADI in die Trennwandler ADuM521x und ADuM621x ist die Reduzierung der Gesamtzahl der Komponenten möglich. Aufgrund des Verzichts auf Oktokoppler können Entwicklungszeit, Zuverlässigkeit und Effizienz optimiert werden. Vier-Kanal-Versionen mit der kleineren, preisgünstigen isoPower-Technologie sind in Entwicklung.

DC-DC-Trennwandler reduzieren die Systementwicklungszeit

Durch die Vorzertifizierung der Wandlermodule trägt Analog Devices zur Verkürzung der Systementwicklungszeit bei – im Gegensatz zu diskreten DC-DC-Wandlern aus mehreren Komponenten, die eine kostspielige und zeitaufwändige einzelne Zertifizierung von mehr als zehn Teilen erfordern. Bis auf zwei Bypasskondensatoren benötigen die DC-DC-Trennwandler-Module keine weiteren Komponenten und verringern somit den Entwicklungsaufwand und die Markteinführungszeiten.

Wichtige Funktionsmerkmale der DC-DC-Trennwandler ADuM5010/ADuM6010 und ADuM521x/ADuM621x

  • Kleines Paket: 20-poliges SSOP mit 5 mm Kriechstrecke
