    Hi Philip,

    In OFF mode all registers are reset to their default values, so DEFUVLO would need to be re-configured after every start.

    Section 9.4.1 of the TPS65217 datasheet details the conditions specifically for OFF mode, and the Global State Diagram (Figure 20) shows registers are reset to default for the OFF, SLEEP, and RESET states.
