Product Description

The ADP3198 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 per-

formance Intel processors. It uses an internal 8-bit DAC to read

a voltage identification (VID) code directly from the processor,

which is used to set the output voltage between 0.5 V and 1.6 V.

This device 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 relation-

ship 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 switching stages.

The ADP3198 also includes programmable no load offset and

slope functions to adjust the output voltage as a function of the

load current, optimally positioning it for a system transient. The

ADP3198 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.

The ADP3198 has a built-in shunt regulator that allows the part

to be connected to the 12 V system supply through a series resistor.

The ADP3198 is specified over the extended commercial

temperature range of 0°C to 85°C and is available in a

40-lead LFCSP.
