Intel IMVP-6.5/GMCH Controllers
GMCH Sleep Transition
For GMCH applications ( CLKEN = GND), the system
enters the sleep state by stepping the VID code down to
the deeper sleep VID code. During these VID transitions,
the MAX17528 blanks PWRGD (forced high impedance)
until 20μs after the last VID transition is completed. Upon
reaching the low-voltage code, the system asserts
GFXDPRSLPVR, which is connected to the MAX17528
SKIP and SLOW pins as shown in Figure 2, allowing the
voltage regulator to enter a pulse-skipping mode (for
best light-load efficiency).
Slow GMCH sleep exit: To avoid audible noise, the sys-
tem reduces the exit slew rate to minimize surge cur-
rents from the input capacitors to the output capacitors.
ACTIVE VID
CPU CORE
The exit transition begins by pulling GFXDPRSLPVR
low, followed by LSB VID steps every 2.5μs until the
active VID target is reached (Figure 6).
Fast GMCH sleep exit: When quickly exiting from the
sleep state, the system immediately changes the VID
code to the active VID code (no LSB stepping) and
keeps GFXDPRSLPVR asserted to select the fast
10mV/μs slew rate. Upon completion of the transition,
the system pulls GFXDPRSLPVR low to signal the
beginning of active state operation.
During all VID transitions, the MAX17528 blanks
PWRGD (forced high impedance) until 20μs after the
internal target (which moves at the slew rate set by
R TIME ) reaches the selected VID code.
