PVI mode - on-the-fly VID transitions
●
SVI mode.
As soon as the controller receives a new valid command to set the VID level for one (or
both) of the two sections, the reference of the involved section steps up or down
according to the target-VID with a 3 mV/
μsec. slope (Typ). until the new VID code is
reached.
If a new valid command is issued during the transition, the device updates the target-
VID level and performs the on-the-fly transition up to the new code.
Pre-PWROK Metal-VID OTF-VID are not managed in this case because the Pre-
PWROK Metal VID are stored after EN is asserted.
●
V_FIX mode.
L6717 checks for SVC/SVD modifications and, once the new code is stable, it steps the
reference of both sections up or down according to the target-VID with a 3 mV/
μsec.
slope (Typ). until the new VID code is reached.
OV, UV and PWRGOOD are masked during the transition and re-activated with a 16 clock
cycle delay after the end of the transition to prevent from false triggering.
