Neue, isolierte Low-Power-Flyback-Gleichspannungswandler

Die ohne Optokoppler auskommenden Sperrwandler stellen eine stabile Ausgangsspannung zur Verfügung und eignen sich für kleine und hochzuverlässige isolierte Stromversorgungs-Lösungen

(PresseBox) (Willich-Münchheide/Nürnberg, )
ROHM Semiconductor (Halle 9, Stand 316) präsentiert sein neues IC des Typs BD7F100HFN-LB als Teil seiner Familie isolierter Sperrwandler, die ohne Optokoppler auskommt. Der Einsatz dieses ICs macht das Design eines isolierten Gleichspannungswandlers einfacher, da die notwendige Signalrückführung, die normalerweise mit einem teuren Optokoppler oder einem komplexen Übertrager mit dritter Wicklung implementiert wird, nicht mehr erforderlich ist. Die dadurch ermöglichte drastische Reduzierung des Bauteileaufwands und der Leiterplattenfläche ergibt eine kompakte und hochzuverlässige isolierte Stromversorgungs-Lösung.

Das IC arbeitet mit der von ROHM entwickelten Adapted-Type ON-Time Control Technology zur Regelung der Ausgangsspannung, deren Höhe mit externen Widerständen und über das Windungsverhältnis oly xmukdiqqptp treyzwqxzv ubdh.
