Is there any voltage regulator with I2C bus so that its output voltage can be programmed as any value (e.g. 3V~6V @ 2A)

Hello user5035929 ,

What is the input voltage planned to be used for this variable output regulator?

The input voltage determines whether your question goes to the Buck or Boost product teams.

Thanks ED,

The input voltage is 9V or 12V DC. Because these kind of power supply can be easily bought from market.

I would like to embed this IC into PCB board.

Jack,

We have some devices, but they program to lower output voltages like 0.8 to 1.95V. Are those of any interest? Otherwise, you can use a digital potentiometer as the lower resistor divider to set the output of many converters. Most of our full feature devices are designed around much higher output currents. Let me know if any of those are of interest to you.

Thanks John,

Unfortunatelly 0.8~1.95V voltage range is too low for me. So I will use DAC chip to output voltage to some regulator IC (e.g. TPS563249) VFB pin so as to adjust the output voltage.

Thanks again

Jack
