Hi!

Our customer will use TPS65233 device. Our customer have some question for used diodes.

If see TPS65233EVM Schematic, Diodes exist as follow.

- D1(B230A) : Is Function protection reverse voltage?

- D131(IN4007) : What is function? If see BOM list, This part is N.C

- D132(BAT43) : What is function? Is Function Surge Protection? If see BOM list, This part is N.C

I attach TPS65233EVM. Please reply to me as soon as possible.

    This is BOOST Schottky Diode. Without this diode, it can not boost BOOST PIN voltage up.  

    - D131(IN4007) : What is function? If see BOM list, This part is N.C

    It's LNB PIN positive surge test protection device. You can add it or delete depends on your system requirments.  

    - D132(BAT43) : What is function? Is Function Surge Protection? If see BOM list, This part is N.C

    It's LNB PIN negtive surge test protection device. You can add it or delete depends on your system requirments.


    Thanks. Any further support if you need, please let me know. Thanks.
