These Values are available in the platform Power

Delivery Design Guide (PDDG). Refer to the chapter for

the voltage rail being tested.

These values are dependant on the VR design. Refer to

a properly completed TOB calculator from your VR

controller vendor for TOB values. Efficiency targets are

system dependant as well. Default values are Intel

guidelines and may not represent the design.

These values are ones that are typical for VR12/IMVP7

designs. They should be verified in the PDDG or VR

controller datasheet.
