ADP3207C
7-Bit Programmable,
Multi-Phase Mobile, CPU
Synchronous Buck
Controller
The ADP3207C 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.
The ADP3207C 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
ADP3207C 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.

The ADP3207C is specified over the extended commercial
temperature range of ? 10 ° C to 100 ° C and is available in a 40 ? lead
LFCSP.
The ADP3207CF has a soft ? start time one tenth of ADP3207C.
There are no other differences between the ADP3207C and
ADP3207CF.
