The ADP31961 is a highly efficient multiphase synchronous
buck switching regulator controller optimized for converting a
12 V main supply into the core supply voltage required by high
performance Advanced Micro Devices, Inc. (AMD) processors.
It uses an internal 6-bit DAC to read a voltage identification
(VID) code directly from the processor, which is used to set the
output voltage between 0.3750 V and 1.55 V.
This device uses a multimode PWM architecture to drive the
logic-level outputs at a programmable switching frequency that
can be optimized for VR size and efficiency. The phase
relationship of the output signals can be programmed to provide
2-, 3-, or 4-phase operation, allowing for the construction of up to
four complementary buck switching stages.
The ADP3196 supports a programmable slope function to
adjust the output voltage as a function of the load current so
that it is always optimally positioned for a system transient.
This can be disabled by connecting Pin LLSET to Pin CSREF.
