Innovative 48V AI power architecture delivers both high current density and high current gain
Vicor 48V Factorized Power Architecture slashes thermal losses and delivers high current density to meet the extreme power demands of AI processors
48V Factorized Power Architecture™ slashes thermal losses and outperforms multiphase approach when powering AI
AI hardware faces severe power and cooling limits. Engineers debate 48V vs. 6V intermediate buses alongside new vertical power delivery (VPD) structures
