GENERAL DESCRIPTION
The ADP3162 is a highly efficient dual output synchronous
buck switching regulator controller optimized for converting a
5 V or 12 V main supply into the core supply voltage required by
high-performance processors such as Tualatin. The ADP3162
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 1.05 V and 1.825 V. The ADP3162 uses a
current mode PWM architecture to drive two logic-level outputs
at a programmable switching frequency that can be optimized
for VRM size and efficiency. The output signals are 180 degrees
out of phase, allowing for the construction of two complementary
buck switching stages. These two stages share the dc output
current to reduce overall output voltage ripple. An active cur-
rent balancing function ensures that both phases carry equal
portions of the total load current, even under large transient
loads, to minimize the size of the inductors.
The ADP3162 also uses a unique supplemental regulation tech-
nique called active voltage positioning to enhance load transient
performance. Active voltage positioning results in a dc/dc converter
that meets the stringent output voltage specifications 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
ADP3162 also provides accurate and reliable short circuit pro-
tection and adjustable current limiting.
The ADP3162 is specified over the commercial temperature
range of 0
°C to 70°C and is available in a 16-lead narrow body
SOIC package.
