  • RE: BQ25173-Q1: Consultation on the charging scheme for 80,000 uF electrolytic capacitors

    Resolved
    Hello The BQ25173-Q1 would not be a good fit for this application. It is a linear regulator with no boost capability. Low input voltage from the battery, 2.5V-3.2V will make it challenging. The TPS 923610 may be an option and will change title.
