TPS55288: Starting up the power supply

Part Number: TPS55288
Other Parts Discussed in Thread: LM5176, ,

Hi Team,

May I ask for your confirmation and advise? Our customer have a concern as shown below:

"Is there a way  to start-up the power supply switching without using the I2C? Or is there a matching part which doesn't need the I2C to start the switching?"

While looking further to help our customer, I saw this e2e post below:

(3) TPS55288-Q1: Working without I2C - Power management forum - Power management - TI E2E support forums

I just want to confirm that it is the same for TPS55288(catalog rating) where I2C is necessary to turn on the device? Also hope to received further advise about a matching part which doesn't need the I2C to start the switching as mentioned by the customer. Is LM5176 ok? Thank you so much.

Kind regards,
Gerald
