Stromversorgung für  Broadcom-,  Cavium- und  Barefoot-Prozessoren

Es gibt zahlreiche Prozessoren für kabelgebundene Netzwerk- und Rechenzentrumanwendungen, die in Verbindung mit einer optimierten Stromversorgung Skalierbarkeit, hohen Durchsatz, hohe Leistungsdichte, vollständige Virtualisierung und große Leistung bieten. Zu diesen Produkten gehören die für den Einsatz in Rechenzentren und Cloudanwendungen optimierten Prozessorplattformen Broadcom Strata XGS® Tomahawk, Cavium ThunderX2™ und Barefoot Networks Tofino™ . Diese äußerst leistungsfähigen Prozessoren mit hohem Integrationsgrad benötigen adaptive und zuverlässige Stromversorgungslösungen, die hohe Leistungsdichte, großen Wirkungsgrad, bestmögliche Regelgenauigkeit und intelligente digitale Schnittstellen bieten.
