Hi Team,

How we can determine/find the correlation between converter operation mode (buck or buck-boost) and VBUS, VBAT voltage?

Hi Kazuto,

Converter will automatically detect based off of duty cycle, and seamlessly transition between modes, so no external host control is required to transition between modes.

Hi Kedar,

I understood it's automatically controlled. However I want to know how the internal control logic changes the converter mode, for example what the criteria to change the mode between boost and buck-boost depending on VBUS and VBAT.
