11 Dynamic VID Transitions

27/44

Caution:

If the new VID code is more than 1 LSB different from the previous, the device will execute the

transition stepping the reference with the DVID-clock frequency FDVID until the new code has

reached: for this reason it is recommended to carefully control the VID change rate in order to

carefully control the slope of the output voltage variation especially in VR10 mode.

Warning:

DVID sample and hold clock depends on the switching frequency FSW. To correctly perform

DVID transition so following the VID change rate, it is required to have at least 2 complete

cycles of the FDVID clock between every VID transition. If the VID update-rate is, for example,

µsec., the minimum operating frequency results to be FSW > 133kHz in VR10 mode.
