Hello,

Rather simple question - can the device startup when the output has a voltage on it?

Thank you!

Hi Jason,

Yes. Please make sure the pre-biased voltage is not exceeding the ABS voltage of Vout 6V.

Hi Zack,

Thanks! Does the operating mode matter for pre-bias startup? I am asking since I saw a couple other questions in regards to the different modes and back current.

Thanks again!

Hi Jason,

Can you specify what kind of questions did you see or show us the back current waveform?
