GENERAL DESCRIPTION

ILIMIT

SW4

The ADP3168 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 Intel processors. It uses an internal 6-bit DAC to

read a voltage identification (VID) code directly from the

processor, which is used to set the output voltage between

0.8375 V and 1.6 V, and uses a multimode PWM architecture to

drive the logic-level outputs at a programmable switching

frequency that can be optimized for VR size and efficiency. The

phase relationship of the output signals can be programmed to

provide 2-, 3-, or 4-phase operation, allowing for the construc-

tion of up to four complementary buck switching stages.

REFERENCE

The ADP3168 also 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 ADP3168 also provides accurate and

reliable short-circuit protection, adjustable current limiting, and

a delayed Power Good output that accommodates on-the-fly

output voltage changes requested by the CPU.
