GENERAL DESCRIPTION

The ADP3194¹is a highly efficient, multiphase, 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 Intel processors. It uses an internal 6-bit

DAC to read a voltage identification (VID) code directly from

the processor that is used to set the output voltage between

0.8375 V and 1.6 V. The device uses a multimode PWM archi-

tecture 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 construction of up to four complementary buck switch-

ing stages.

The ADP3194 also includes programmable, no-load offset,

and slope functions to adjust the output voltage as a function

of the load current, so it is always optimally positioned for a

system transient. The ADP3194 also provides accurate and

reliable short-circuit protection, adjustable current limiting,

and a delayed power good output that accommodates on-the-

fly (OTF) output voltage changes requested by the CPU.

The devices are specified over the commercial temperature

range of 0°C to +85°C and are available in a 28-lead TSSOP.
