Product Description


ADP3181  5-Bit or 6-Bit Programmable 2-,3-,4-Phase

                Synchronous Buck Controller


The ADP3181 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 performance Intel processors. It uses an internal 6-bit
DAC to read a voltage identification (VID) code directly from
the processor, which is used to set the output voltage. The
CPUID input selects whether the DAC codes match the
VRM 9 or VRD 10 specifications. It 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 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-switching stages.

The ADP3181 also includes programmable no-load offset and
slope functions to adjust the output voltage as a function of the
load current so that it is always optimally positioned for a
system transient. The ADP3181 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 device is specified over the commercial temperature range
of 0°C to +85°C and is available in a 28-lead TSSOP package.
