15、logies AG 2024.All rights reserved.Aug 2024restrictedSummary&Key take-aways AI server SMPS higher power is reached by scaling up the number of interleaved stages and using lower Rds_on devices.Further higher power requirement will push the SMPS to 3-Phase topologies(e.g.:Vienna)and higher DC voltage

16、 distribution(ex:380V).AI servers show significant higher power trend,and possibly new rack architecture and cooling.Top side cooling packages can be an enabler for new cold plate liquid cooled SMPS.Infineon CoolGaNTMLeads the Way in Next-Generation AI Server SMPS Together with Si and SiC Power Technologies20
