This voltage can be changed later by writing the VSW4_RUN[7:0] bits in the&nbsp;SW4 RUN VOLT register through I2C.&nbsp;</P> <P>Best regards,</P> <P>Tomas</P> Thu, 15 Sep 2022 12:54:30 GMT https://community.nxp.com/t5/Power-Management/PF8100-setting-output-voltage/m-p/1522937#M2157 TomasVaverka 2022-09-15T12:54:30Z
