TPS55288-Q1: Working without I2C

Israel Rosner1

Part Number: TPS55288-Q1
Other Parts Discussed in Thread: LM5176-Q1

Hi,

according to the webench i saw i must use the I2C connection. but than i couldn't find in the datasheet how the output voltage is determined.

so my question is if i must use I2C to program it? If the answer is yes, you must emphasize it on the Webench.

can you suggest me other equivalent part? i need a 12V 5A output getting 8-36V from car battery, AEC-Q100.

thanks,

Israel

i had a mistake - in the Webench design the I2C lines are not connected

Hello Israel,

I2C is necessary to turn on the device. There is a default setting for the output, but I do not know if this fits your needs.

Do you want to use a part which does not need I2C communication? If yes, my suggestion would be LM5176-Q1.
