Other Parts Discussed in Thread: LP8754

Dear TI

Customer are using EVM of LP8754 and they have some questions.

When connected USB interface board which is USB-TO-I2CEVM to EVM without power supply, output voltage of LP8754 was 0.7V.

They would like to know the reson why output became 0.7V without power supply.

Is there any power path from USB interface board to LP8754?

Is it correct?

Thank you for your cooperation

K.Narisawa
