GENERAL DESCRIPTION
The ADP3180 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 6-bit DAC to read
a voltage identification (VID) code directly from the processor,
which is used to set the output voltage between 0.8375 V and
1.6 V, and 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 comple-
mentary buck switching stages.
The ADP3180 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 ADP3180 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.
ADP3180 is specified over the commercial temperature range of
0°C to 85°C and is available in a 28-lead TSSOP package.
