TPS7A78: TPS7A78 for high frequency application

Part Number: TPS7A78

Hi, Team,

I have 2 questions for TPS7A78.

1. Can TPS7A78 support the below DC input condition?

2. Is it possible to use TPS7A78 for 100Hz~900Hz AC power?

Best Regards,

Satoshi Yone

  • Hello Satoshi-san,

    1. TPS7A78 DC supply mode is limited to 23V as specified in recommended operating condition table. Also DC supply mode is only available for Vout <= 3.6V

    2. Yes 100 Hz to 900 Hz within AC supply mode frequency, to properly calculate the cap-drop capacitor (Cs), please refer to section of TPS7A78 datasheet for detailed explanation.
