GENERAL DESCRIPTION
The ADP3166 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 AMD processors. It uses an internal 5-bit DAC to
read a
voltage identification (VID) code directly from the pro-
cessor, which is used to set the output voltage between 0.8 V
and 1.55 V. The ADP3166 also uses a multimode PWM
archi
tecture to drive the logic-level outputs at a programmable
switching frequency that can be optimized for VRM 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 switch-
ing stages.
The ADP3166 includes programmable no-load offset and slope
functions to adjust the output voltage as a function of the load
current so that it is always optimally positioned for a system
transient. The ADP3166 also provides accurate and reliable
short-circuit protection, adjustable current limiting, and a delayed
power good output that accommodates on-the-fly output volt-
age changes requested by the CPU.
ADP3166 is specified over the commercial temperature range of
0
°
C to 85
°
C and is available in a 28-lead TSSOP package.
