Destin\u00e9 \u00e0 l\u2019alimentation de cartes IA (Intelligence artificielle) \u00e0 GPU (Graphics Processor Unit, ou processeur graphique) ou \u00e0 module OAM (module acc\u00e9l\u00e9rateur OCP), le ChiP-set 4609 est d\u00e9j\u00e0 produit en s\u00e9rie et il est disponible pour les nouveaux clients sur la carte d’\u00e9valuation Hydra II de Vicor.<\/p>\n

Le 4609 ChiP-set vient s’ajouter au portefeuille Power-on-Package de Vicor, qui regroupe plusieurs solutions de distribution de puissance lat\u00e9rale (LPD pour Lat\u00e9ral Power Delivery). Afin de pouvoir fournir des courants d\u00e9passant les limites de la technologie LPD, Vicor fait \u0153uvre de pionnier avec sa distribution de puissance verticale (VPD pour Vertical Power Delivery), qui permettra bient\u00f4t des densit\u00e9s de courant encore plus \u00e9lev\u00e9es. La technologie VPD fournit le courant \u00e0 partir de convertisseurs de puissance positionn\u00e9s directement sous le processeur, gr\u00e2ce \u00e0 un r\u00e9seau de condensateurs dispos\u00e9s selon le brochage sp\u00e9cifique du processeur \u00e0 alimenter. Un GCM (\u00ab\u00a0Geared Current Multiplier\u00a0\u00bb) est une version de VPD sp\u00e9cialis\u00e9e, dont le r\u00e9seau de condensateurs \u00ab\u00a0Gearbox\u00a0\u00bb constitue l\u2019une des couches de la pile verticale. En distribuant le courant directement sous le processeur, et en \u00e9liminant les pertes PDN, les GCM permettront bient\u00f4t d\u2019atteindre des densit\u00e9s de courant de 2 A\/mm2.<\/p>\n
