Part Number: BQ25120A

Hi all,

Just wondering if it is possible to set the buck converter output voltage to 3V without a host MCU (I2C) interface?

Regards,

Hello,

The default VSYS voltage is 1.8V. To adjust the voltage, you'll need to communicate with the device through I2C. Why do you need 3V if i may ask.

Thanks for the feedback Raheem. I am in the process of part selection for my board and a component requires between 2.7V-3.6V. I’ll try to find an alternative.
