We are trying to fix a client's design using the TPS55288. The I2C pins SDA and SCL are not connected. Is it possible to use the TPS55288, with an external resistor divider at the FB pin, without having an I2C connection to configure it at start-up?

Hi Kerry,
You can select TPS552882, the non-i2c buck-boost converter. This device will start switching once EN is high and Vin is higher than VIN_UVLO. The output voltage is configured with the external feedback divider.
