ADP3207D

7-Bit Programmable,

Multi-Phase Mobile, CPU

Synchronous Buck

Controller

The ADP3207D is a high efficiency, multi−phase, synchronous,

buck−switching regulator controller optimized for converting

notebook battery voltage into the core supply voltage required by high

performance Intel processors. The part uses an internal 7−bit

Digital−to−Analog Converter (DAC) to read Voltage Identification

(VID) code directly from the processor that sets the output voltage.

The phase relationship of the output signals can be programmed to

provide 1−, 2−, or 3−phase operation, allowing for the construction of

up to three interleaved buck−switching stages.

MARKING DIAGRAM

The ADP3207D uses a multi−mode architecture to drive the

logic−level PWM outputs at a programmable switching frequency that

can be optimized depending on the output current requirement. The

part switches between multi−phase and single−phase operation to

maximize its effectiveness under all load conditions. In addition, the

ADP3207D includes a programmable slope function to adjust the

output voltage as a function of the load current. As a result, it is always

best positioned for a system transient.

The chip 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.

= Pb−Free Package

The ADP3207D is specified over the extended commercial

temperature range of −10°C to 100°C and is available in a 40−lead

LFCSP.

ORDERING INFORMATION

See detailed ordering and shipping information in the package

dimensions section on page 31 of this data sheet.

The ADP3207DF has a soft−start time one tenth of ADP3207D.

There are no other differences between the ADP3207D and

ADP3207DF.
