Hi, Team,
I have 2 questions for TPS7A78.
1. Can TPS7A78 support the below DC input condition?
Vin:~190Vdc
Vout:6V?
Iout:~0.1A
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 8.2.2.1 of TPS7A78 datasheet for detailed explanation.
