TPS53647: output voltage margining in pin strap mode

Ben Kuo

Part Number: TPS53647

Dear team,

Customer now set our TPS53647 in pin strap mode and need to control output voltage(margining higher/lower Vout) during power on by I2C/PMBUS.

Is there any risk about this application?

Per my understood, pin strap set Vboot by external resistor and we can write VOUT_COMMAND to change output voltage by digital interface after power on.

Please share your comments with us, thanks.

Regards,

Ben
