Vicor 4609 chipset

Vicor has announced the 4609 chipset for high-performance GPU, CPU and ASIC (XPU) processors powered directly from 48 V. A driver, MCD4609, and a pair of MCM4609 current multiplier modules supply up to 650 A continuous and 1200 A peak power. Owing to their small footprint and low profile (45.7 x 8.6 x 3.2 mm), current multipliers are placed close to the processor enabling reduced power distribution network (PDN) losses and higher power system efficiency.

Powering GPU and OCP Accelerator Module (OAM) artificial intelligent (AI) cards, the chipset is available on the Vicor Hydra II evaluation board. The product adds to the Vicor Power-on-Package portfolio of Lateral Power Delivery (LPD) solutions, enabling high current density and efficient current delivery for advanced processors in applications including AI accelerator cards, AI high-density clusters and high-speed networking.
