GENERAL DESCRIPTION

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 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 is specified over the commercial temperature

range of 0°C to 70°C and is available in a 16-lead narrow body

SOIC package.
