GENERAL DESCRIPTION

PRECISION

LLSET

The ADP3192¹is 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.

Figure 1.

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 ADP3192 has a built-in shunt regulator that allows the part

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

The ADP3192 is specified over the extended commercial

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

40-lead LFCSP.

The ADP3192 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

ADP3192 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.
