Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
Evidence
The benefit of moving 50VDC-12VDC conversion closer is to the reduce current and increase transmission efficiency
Context After
We have the volume and ASP for all the power semis for the all the various VRMs contained in the VR NVL72 Component BoM and Power Budget Model ↗.
② Atomic Claim
把 50VDC→12VDC conversion 移得更靠近負載端，可降低 current 並提升 transmission efficiency。
