TPS61287: Chip Capacitor Selection

Part Number: TPS61287

Tool/software:

Hello Fergus,

Good day. For TPS61287EVM-042 TPS61287 Synchronous Boost Converter Evaluation Module, is it recommended to have 22uF 25V chip capacitor for a 20V output circuit? Can we replace these 22uF 25V output capacitors (Cout) with 10uF 35V instead because chip capacitor 22uF with higher than 25V is not commonly used. Thank you!

  • Hi Hau,

    Thank you for reaching out.

    Of course, 10uF/35V can be used as the output capacitors.

    The ceramic capacitors are used to absorb most of the output ripple and please ensure effective capacitance.

    Best Regards,

    Fergus
