Part Number: TPS53681

Hi：

 How many times can TPS53681 NVM save user configuration？

TPS53681 controller whether different voltage settings are supported for VBOOT and VOUT_COMMAND，for example VOUT_COMMAND=0.80V，VBOOT=0.86V？

If this application is supported, how can VBOOT=0.86 voltage jump to VOUT_COMMAND=0.80V voltage？

thanks

    Hi,

    1. TPS53681 can support at least 1000 times NVM written.

    2. After TPS53681 initialization (3.3V is ready), VOUT_COMMAND will be the same as VBOOT. Then after device boot up to VBOOT, you can send out the desired voltage to VOUT_COMMAND to change VOUT.

    Thanks
