I have a project where the voltage needs to be adjusted to 0.44V. The chip cannot be replaced at the moment. Which resistor value can be used for TDA38740? Thank you.

Hello @ymye ,

One way is to set the vboot_override_pin to 1 and then use the VOUT_COMMAND to set the output voltage to 0.44V

The resistor at the VBOOT pin can also be tuned to obtain the required output voltage but the telemetry values will not be correct and hence it is usually not recommended.

Regards,

Nishanth
