ISL6563
DYNAMIC VID (VID-ON-THE-FLY)
The ISL6563 is capable of executing on-the-fly output
voltage changes. The way the ISL6563 reacts to a change in
the VID code is dependent on the VID configuration. In
VRM9 or AMD Hammer settings, the ISL6563 checks for a
change in the VID code four times each switching cycle. The
VID code is the bit pattern present at pins VID4-VID0. If a
new code is established and it stays the same for 12
switching cycles, the ISL6563 begins changing the reference
by making one step change every four switching cycles until
it reaches the new VID code. Figure 5 depicts such a
transition, from 1.5V to 1.7V
