Figure 2-6is an example of dynamic VID. The diagram assumes steady state, constant current during the dynamic VID transition for ease of illustration; actual processor behavior allows for any dIcc/dt during the transitions, depending on the code it is executing at that time. Note that during dynamic VID, the processor will not output VID codes that would disable the voltage regulator output voltage.

The processor load may not be sufficient to absorb all of the energy from the output capacitors on the baseboard, when VIDs change to a lower output voltage. The VRM/ EVRD design should ensure that any energy transfer from the capacitors does not impair the operation of the VRM/EVRD, the AC-DC supply, or any other parts of the system.
