Dual Output 3+1 Phase PWM Controller The uP9531Q is an AMD® SVI2 compliant mobile CPU voltage regulator controller that integrates a 3-phase PWM controller for VDD and a 1-phase PWM controller for VDDA. The VDD controller can be configured as 3/2/1-phase, and the VDDA controller can be configured as1/0-phase (0 denotes VDDA controller is disabled) for platform power design flexibility. This device has 3 embedded 5V MOSFET drivers with integrated bootstrap diodes. This device combines true differential output voltage sense, inductor DCR current sense, input voltage sense and adaptive voltage positioning to provide accurately regulated voltage for mobile CPU. It adopts uPI’s proprietary RCOT+TM (Robust Constant On-Time) control ... |
