GENERAL DESCRIPTION

loop has been optimized for conversion from 12 V, while the

ADP3167 is designed for conversion from a 5 V supply.

The ADP3160 and ADP3167 are highly efﬁcient, dual output,

synchronous buck switching regulator controllers optimized for

converting a 5 V or 12 V main supply into the core supply voltage

required by high-performance processors, such as Pentium 4 and

Athlon. The ADP3160 uses an internal 5-bit DAC to read a volt-

age identiﬁcation (VID) code directly from the processor that is

used to set the output voltage between 1.1 V and 1.85 V. The

devices use 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 current 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 ADP3160 control

The ADP3160 and ADP3167 also use a unique supplemental

regulation technique 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. They also provide accurate and reliable short

circuit protection and adjustable current limiting.

The ADP3160 is speciﬁed over the commercial temperature

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

SOIC package.
