TPS62877-Q1: Alternate suggestion

Balkis Mahammad
Prodigy 140 points
Part Number: TPS62877-Q1

Hi Team,

Am looking for buck regulator for my new design and I have requirement of 3.3 volt input and 0.6 minimum voltage for 10A to 30A current.

While exploring came across TPS6287-Q1 part, which is suitable for all input and output voltages, but this part is auto motive grade, is there any alternate with non automotive grade?

Also I will not be using scl/sda for this part, is that ok?

Thanks and Regards,

Balkis

    Hello Balkis,

    there is currently no single device non-automotive solution to provide 30A output current.

    However, you may explore the option to use two TPS62873 15A devices in a stack. This increases the solution size, but also brings advantages like lower device temperature.

    Details can be found in the datasheet (section 9.3.17) and in this app note: https://www.ti.com/lit/an/slvafh4/slvafh4.pdf

    Regarding your second question about I2C pins:

    If you do not plan to use the I2C interface, please connect the SDA and SCL pins to GND.

    Please let me know, if you have further questions.

    Best regards,

    Werner
