Set DRVEN output function at PS4. Set to 5V DRVEN is floating, and set to
GND DRVEN is low at PS4.
PWM outputs for auxiliary rail VR.
Thermal sense input for AUXI rail VR.
Negative input of the error amplifier. This pin is for auxiliary rail VR output
voltage feedback to controller.
Return ground for auxiliary rail VR. This pin is the negative node of the
differential remote voltage sensing.
Auxiliary rail VR compensation. This pin is error amplifier output pin.
Auxiliary VR voltage sense input. This pin is connected to the terminal of
Main VR output voltage.
Negative current sense input of single-phase auxiliary Rail.
Positive current sense input of single-phase auxiliary Rail.
Auxiliary rail VR current monitor output. This pin outputs a voltage
proportional to the output current.
Thermal monitor output. This pin is active low.
VR and CPU data transmission interface.
SVID alert. (Active low)
Synchronous clock from the CPU.
External driver enable control. Connecting to driver enable pin.
PWM outputs for VCCSA VR.
VR enable control input.
VR ready indicator.
VCCSA rail VR current monitor output. This pin outputs a voltage
proportional to the output current.
