Tool/software:
Hi expert,
Customer used TPS544C26 and try to change Vboot by i2c but failed. They have tried set on/off config to 001b I2C operation command and/or 011b EN pin and Operation command but all failed.
Would you please advise anything need to be aware of?
Regards,
Allan
Hi Allan,
In order to change any parameters, TPS544C26 must be unlock first. Please see attached user's guide. For your case, if you use I2C only, you don't need to change VBOOT (VBOOT is for SVID). You need to change the output voltage in VOUT_CMD as below.

Hope this helps,
Thanks,
