GENERAL DESCRIPTION

ILIMIT

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

architecture 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.
