GENERAL DESCRIPTION
The ADP3164 is a highly efficient 4-phase synchronous buck
switching regulator controller optimized for converting a 12 V
main supply into the core supply voltage required by high per-
formance Intel processors. The ADP3164 uses an internal 5-bit
DAC to read a voltage identification (VID) code directly from
the processor, which is used to set the output voltage between
1.1 V and 1.85 V. The ADP3164 uses a current mode PWM
architecture to drive the logic-level outputs at a programmable
switching frequency that can be optimized for VRM size and
efficiency. The four output phases share the dc output current
to reduce overall output voltage ripple. An active current bal-
ancing function ensures that all phases carry equal portions of
the total load current, even under large transient loads, to mini-
mize the size of the inductors.
The ADP3164 also uses a unique supplemental regulation tech-
nique called active voltage positioning (ADOPT) to enhance
load transient performance. Active voltage positioning results in
a dc/dc converter that meets the stringent output voltage specifi-
cations for high-performance processors, with the minimum
number of output capacitors and smallest footprint. Unlike
voltage-mode and standard current-mode architectures, active
voltage positioning adjusts the output voltage as a function of the
load current so that it is always optimally positioned for a system
transient. The ADP3164 also provides accurate and reliable short
circuit protection, adjustable current limiting, and an enhanced
Power Good output that can detect open outputs in any phase for
single or multi-VRM systems.
The ADP3164 is specified over the commercial temperature
range of 0
°
C to 70
°
C and is available in a 20-lead TSSOP package.
