BQ25713: Duty cycle limit under buck mode

Antony Lin

Part Number: BQ25713

Hi,

For BQ25713 under buck mode, is it there any constraint about the maximum duty cycle? Or is there any minimum voltage difference (Vin-Vout) requirement?

THanks!

Hey Antony,

If the duty cycle gets very high, the charger will transition to the buck-boost region of operation. So the answer is now; although the charger will not be purely in buck-mode at that point.
