TPS61194-Q1: output short testing

Part Number: TPS61194-Q1
Other Parts Discussed in Thread: TPS61194EVM

Hello,

In the TPS61194EVM, there is the 2200pF of C10~C13 capacitors.
I think that these caps for protecting the OUT pin when short circuit condition.
Then I have the question about these caps.

(1) Should we add these caps for protect the device when output short circuit condition?
(2) If yes, how to decide these capacitance value?

 Best Regards,
Ryuji

    Hi Ryuji-san,

    (1) Should we add these caps for protect the device when output short circuit condition?
    No, it's just an option regardless of normal operation. It depends on system requirements for short protection.

    (2) If yes, how to decide these capacitance value?
    It also depends on short status like hard short or ohmic short. 2.2nF is just a recommendation in general.

    Hope this helps,
