Hi TI Expert,
Please refer to below SCH for TPSM861257, our customer would like to adjust the output(original is 3.3V) to 3.7V.
The recommended RFBB=30kOhm based on the datasheet's table 8-2 as below for the output of 3.3V/5V, take the same resistance value of RFBB for 3.7V Vout calculation, the standard resistance can be selected in the range of 154kOhm(Vout=3.68V) to 158kOhm(Vout=3.76V) for the RFBT(R315). Would you please let us know if the RFBT resistance value in the range is suitable as recommended?
Look forward to your feedback soon, thank you.
