ADP3180*的产品描述：

The ADP3180 is a highly effi  cient 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 identifi  cation (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 effi  ciency. 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 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-fl  y output voltage changes requested by the CPU.ADP3180 is specifi  ed over the commercial temperature range of 0°C to 85°C and is available in a 28-lead TSSOP package.
