TPS53318: Comment required on designing for Processor Core Supply of 1.08V 7.5A with AVS control

Karthikeyan Subramanian

Part Number: TPS53318

Dear TI

Please help me in clarifying the following in the design with TPS53318 for Processor Core Supply of 1.08V, 7.5A with AVS control. (a) I hope this device can support the AVS control from Processor, which varies in the range of Vo-0.2V to Vo+0.2V (b) Please confirm the AVS control provided as shown in the schematic picture, which is updated from the design generated from web-bench without AVS control.

The web-bench in puts and output is also given below for reference

Thanks and Regards

You should be able to margin the output voltage. We have a reference design for 2 bit VID scaling.

Thanks John. I feel the resistor values used in the FB are correct for the expected result.
Can you please provide link for looking at the reference design?
