Freescale liefert integrierte Stromversorgungslösung für 'Power over Ethernet'-Geräte

Single-Chip PoE-Controller eröffnet Entwicklern ein höheres Maß an Flexibilität und Integrationsdichte für Geräte, die über Ethernet mit Strom versorgt werden sollen

(PresseBox) (PARIS, )
Die 'Power over Ethernet'-Technologie (PoE) ist weiter auf dem Vormarsch. Im Vergleich mit herkömmlichen Netzteilen bietet sie nämlich deutliche Kostenvorteile und ein Mehr an Flexibilität. Als Reaktion auf die wachsende Nachfrage hat Freescale Semiconductor (NYSE:FSL, FSL.B) unter der Typenbezeichnung MCZ34670 einen Single-Chip PoE-Controller vorgestellt. Dieser besteht aus der Kombination eines PD-Interface-Ports (Powered Device) nach dem IEEE 802.3af PoE-Standard und eines PWM-Controllers (Pulse Width Modulator). Dank des hohen Integrationsgrades können Ingenieure mit einem Minimum an externen Komponenten zu geringeren Kosten und äußerst flexibel Endgeräte entwickeln, die ihre Energie über den Ethernetanschluss beziehen.
