bq24103A can 100% duty operation.
If input voltage is 8.4V, bq24103A operates 100% duty for 8.4V charging voltage.
But there are Rdson of FET and DCR of inductor.
So I think that bq24103A can't output 8.4V.
In this case, does bq24103A operate correctly? Is teh CC-CV control done without problem?
How about bq24105 when input voltage is 8.4V and charging voltage is 8.2V?
I think that bq24105 can't output 8.2V because of FET's Rdson and Inductor's DCR.
