TPS631013: IC substitute material inquiry

Hi Team

Do we currently have a Buck-Boost IC that can meet this need?
In addition, customers have requirements that the output voltage (primary), current (primary), and temperature (secondary) status must be known through the "communication function"

A. The input is about 4.2V, the output is 3.8V, and the output current is 3A.
B. The input is about 4.2V, the output is 4.6V, and the output current is 3A.

Thanks

Hi Boyan,

Thank you for reaching out. For this power stage we have TPS55289(I2C version).

Customer can use I2C to set output voltage, so the output current is known. We have CDC pin for output current indication. Customer can use ADC to read the output current. We don't have indication for temperature. But we have indication for OTP.

Regards,

Mulin

Hi Boyan,

Could we know project information such as application, platform, MP schedule, run rate?

Hi Mulin

So we don't have an IC that can read the output voltage directly via I2C right?

Regarding TPS55289, does it read the output current through I2C?

I can give you the customer's application information via webex after I confirm it.

Thanks,
Boyan

Hi Boyan,

Yes, currently we can't read output voltage and current I2C. Customer need to use external ADC circuit. Why customer needs this function?
