uP6208
12 Phase Synchronous-Rectified Buck Controller
for Next Generation CPU Core Power
General Description
Features
The uP6208 12-phase PWM control IC provides a precision voltage regulation system for advanced microprocessors. It can work with Intel VR11/VR10 and AMD 5/6-bit VID table. The controller also includes programmable no-load offset and active voltage positioning functions to adjust the output voltage as a function of the load current, so it is optimally positioned for a load current transient. Continuous DCR current sensing is used for load line programming and channel current balance. The uP6208 also provides accurate and reliable over current protection, over voltage protection and a delayed power good output.
