Part Number: TPS65311-Q1

While i am in active state am i able to use the PWR_CONFIG register to disable power supplies in a determined sequence and than transition into LPM0 mode so buck 1 is turned off last?

    Hi Julio,

    Reading through the datasheet, it looks like writing the BUCKx_EN bits to 0 should disable the bucks and they can determine that sequence by the SPI write order, though it will be immediate. Then LPM0 can be entered and they will have already been disabled.

    I've looped in our expert in case there is more to it than that.
