Tool/software:

Hi Team,

I want to check if TPS62813-Q1 can support AVS(Adaptive Voltage Scaling) or not.

As I know, AVS is using the external circuit to control the Vout. Not sure if it has any limitation or not?

Hi Roy,

In general this is possible. However, it would be better to share the exact schematic you would use to confirm.

Thanks,

Febin

Hi Febin,

The highlighted section below is the Adaptive Voltage Scaling Circuit that was derived from the supplier’s “GW5 Board Design Guidelines” application note.

May you help review the schematic?

Regard,

Roy

Hi Roy,

Only part of the schematic is visible. What is Rcf value?

Just to be clear, what are the voltages that will be used?

Regards,

Febin
