TPS65910 VDD2 datasheet discrepancies

Frank D'Aliesio

Hello:

I see the following table from the datasheet p27, table 2 fixed boot mode 00

VDD2_OP_REG/VDD2_SR_REG = VDD2 voltage level selectiion for boot = 1.1V.

But on table 2 page 29 it has VDD2=3.3V.  They appear to contradict one another for VDD2 voltage level.  Can you explain further or can you tell me which is correct?

At the root of all this, I don't understand what this table 2 is telling me.  Can you clarify both points for me (what the table means and if there is an error in the voltage level, which is correct)?

Thank you

    Hi Frank,

    Thanks for your post.

    Your comment is absolutely valid "On page 27 datasheet  table 2 fixed boot mode 00. VDD2_OP_REG/VDD2_SR_REG = VDD2 voltage level selectiion for boot = 1.1V."

    but there is another bit VGAIN_SEL right below "VDD2_OP_REG/VDD2_SR_REG " in the table which shows the gain is set to "3". This bit scales the VDD2 3 times.

    It is just a differnt way bits are presented but there is no discrepency in the table.
