Part Number:BQ24618
I am thinking BQ24618 as a charger for 3-cell battery (12.6V), and BQ24618 datasheet tells it's BUCK converter. I tried to find what the Vin minimum to fully charge 3-cell battery, but unfortunately I could not find such parameter in datasheet; the typical application in datasheet uses 19V for 3-cell, 19V is too high for my power source selection, please advise what Vin-Vout minimum drop voltage is.
