Datasheet Summary
Dual Output 2+1 Phase PWM Controller with 3 Embedded 5V
Drivers for AMD® SVI2 Mobile CPU Core Power
General Description
The uP9531P is an AMD® SVI2 pliant mobile CPU voltage regulator controller that integrates a 2-phase PWM controller for VDD and a 1-phase PWM controller for VDDA. The VDD controller can be configured as 2/1-phase, and the VDDA controller can be configured as1/0-phase (0 denotes VDDA controller is disabled) for platform power design flexibility. The controller provides further flexible operating phase configuration to support 3+0 application. This device has 3 embedded 5V MOSFET drivers with integrated bootstrap diodes. This device bines true differential...
