Hello
I'm confused that what is the best placement for the output capacitor C3.
Should it be placed close to the inductor and VBAT pad like PIC A?
or
close to the Pin 10(BAT) of BQ25303J PIC B?
Thank you!

Hello Ning
Thank you. I've read the EVM design before posting. There are fews cap, some of them are close to the inductor and some is close to pin BAT, that's why I'm confused if I just use one cap. If it's for filtering, should it be close to inductor (PIC A)?
Thanks for your help.
Hi,
Referring to the d/s, Battery voltage sensing input. Connect this pin to the positive terminal of the battery pack and the node of inductor output terminal. 10-µF capacitor is recommended to connect to this pin.
Thanks,
Ning
Hi Ning
Thank you for your prompt reply. the datasheet is something making confused as well. The suggest layout is placeing this cap close to the inductor instead of BAT pin.
If it needs to be close to BAT pin, the layout should be like this
Hope I made it clear.
Thank you!
