TPS62866: TPS62866 A/B version for same design

Part Number: TPS62866

My customer want to design TPS62866 A & B version in same schematic.

Can customer pull A2 pin low to GND with R=105kohm to compatible A & B version ?

According to D/S, pull low = "Vout register 1" for A version. but not same as B version.

Q : Should customer use different I2C setting for A/B version? or can A/B version use same I2C setting?

    Hello user,

    Can you detail here what are the output voltages customer is trying to use for A&B version ?

    If you are using the same configuration with a 105 kohm connected between VSET and GND for A&B version then you will have the same start-up output voltage and I2C address.

    For B version, after start-up the pin will behave a (/Power Good) output.

    Let me know if this helps.

    Thanks a lot!

    Regards,
    Dorian
