TPS53915: converter or controller like TPS53915 but using I2C

Part Number: TPS53915

Hi,

I'm trying to find a converter or controller that could adjust output voltage from 1V to 5V/1A. Seems TPS53915 is a good solution but the interface is PMBus.

Does TI has any converter or controller meet this spec but using I2C as interface?

Thank you.

C.T.

    C.T.,

    The list of I2C compatible buck converters can be found here:

    Looking thru it, I don't see anything that matches your needs.  Perhaps you might consider using an I2C controlled digital potentiometer as the lower feedback divider resistor to adjust the voltage of your favorite buck converter:

    LM2734 or TPS54320 might be good matches.
