General Description

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.
