ADP3186 General Description

The ADP3186 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 AMD processors. It uses an internal 5-bit DAC to read a voltage identification (VID) code directly from the pro-cessor, which is used to set the output voltage between 0.8 V and 1.55 V. 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 relation-ship of the output signals can be programmed to provide 2-, 3-, or 4-phase operation, allowing the construction of up to four complementary buck switching stages.

The ADP3186 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 ADP3186 also provides accurate and reliable short-circuit protection, adjustable current limiting, and a power good output that accommodates on-the-fly output voltage changes requested by the CPU.

The ADP3186 is specified over the commercial temperature range of 0°C to 85°C and is available in 28-lead TSSOP and QSOP packages.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Absolute maximum ratings apply individually only, not in combination. Unless otherwise specified all other voltages re referenced to GND.
