| Features |
The uP9505U is an AMD® SVI2 compliant desktop CPU voltage regulator controller that integrates a 4-phase PWM controller for VDD and a 2-phase controller for VDDA. The VDD controller can be configured as 4/3/2/1-phase, and the VDDA controller can be configured as 2/1/0-phase (0 denotes VDDA controller is disabled) for platform power design flexibility. For the typical 4+2-phase application, the 4-phase VDD controller has 4 PWM outputs. The 2-phase VDDA controller has 2 PWM outputs. The controller provides further flexible operating phase configurations to support 6+0 or 5+1 phase application (...
