bq24086 / input pulse current

S.Satoshi

Hi Everyone,

Please see the waveform in attached which is confirmed our customer's preproduction board. They confirmed pulse current when the change enabled. Do you have experience that such pulse current was any issue?

Our customer is asking it because they have experience to see issue with such pulse current by using competitor's device in past model.

There will be a pulse of current to charge the output capacitor. This should not be an issue. The input capacitor should be as close as possible between the input and GND pins of the IC.

Hi Jeff-san,

Thank you for your comment. I understand that this pulse should be charging current into output capacitor.

Best Regards,
