Datasheet Summary
Dual Output 3+1 Phase PWM Controller with 3 Embedded 5V Drivers for AMD® SVI2 Mobile CPU Core Power
General Description
The uP9531Q is an AMD® SVI2 pliant 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 bines true differential output voltage sense, inductor DCR current sense, input voltage sense and adaptive voltage...
