uP9531Q Datasheet (uPI Semiconductor) - Dual Output 3+1 Phase PWM Controller

uP9531Q, 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
