FUNCTIONAL DESCRIPTION
General
The NCP5392P provides up to four-- phase buck solution
which combines differential voltage sensing, differential
phase current sensing, and adaptive voltage positioning to
provide accurately regulated power necessary for both
Intel VR11.1 and AMD CPU power system. NCP5392P has
been designed to work with the NCP5359 driver.
AUTO--PSI Function
NCP5392P makes energy saving possible without
receiving PSI signal from the CPU by wisely introducing
Auto-- PSI feature. The device will monitor VID lines for
transition into/out-- of Low Power States. When the VID
drops (An indication of entering power saving state), the
Auot-- PSI logic will detect the transition and enable PSI
mode. On the other hand, when the VID rises (exiting
power saving mode), the Auto-- PSI logic detects the
transition and exit PSI mode automatically. Auto-- PSI uses
the dynamic VID(DVID) transitions of VR11.0 and
VR11.1 to shed phases. The phase shedding improves the
efficiency of the Vcore regulator eventually. In PSI mode,
the total current limit is reduced by the ratio of the phase
count left after phase shedding.
Auto-- PSI function can be activated and deactivated by
toggling APSI_EN (PIN38), but with lower priority
compared to PSI signal. When PSI (PIN37) is pulled to low,
the system will be forced into PSI mode unconditionally,
and APSI_EN signal will be shielded.
NCP5392P can be operated up to four phases. It can be
configured as 1 or 2 phase operation when the system enter
PSI mode automatically (for example, VID down from 1.2 V
to 1.1 V). Choice of going down to 1 or 2 phases can be set
up by Pin40--PH_PSI. PH_PSI=high means one--phase
operation. PH_PSI=low means two-- phase operation.
Remote Output Sensing Amplifier(RSA)
A true differential amplifier allows the NCP5392P to
measure V core voltage feedback with respect to the V core
ground reference point by connecting the V core reference
point to VSP, and the V core ground reference point to VSN.
This configuration keeps ground potential differences
between the local controller ground and the V core ground
