TPS62873-Q1: Adjusting output voltage

Part Number: TPS62873-Q1


I was thinking of using the TP62873-Q1 as a 1.8V regulator, however I won't have I2C available in my design. Since there aren't any TPS6287xY2-Q1 available yet I'd need to adjust the output voltage as in your Adjusting the Output Voltage of a Fixed Output Voltage DC-DC Converter application note.

My concern here is this would mean a 80% output increase from a VSEL value of 1.0V, which is a lot compared to the recommended 20%. Would it be possible to get 1.8V as an output with this approach or should I go with another option?
