TPS56428: Could you please tell me this device operation under output short condition?

hi,
refer to datasheet page 10: 8.4.3 Current Protection.
if Vout short to GND, device will enter hiccup mode. it is a protection mode and the device will be protected without damage.

Hello Jason,

Thank you very much for the prompt reply.
Could I ask you an additional question?
Is the repeat time of restart in hiccup mode 7us (Typ)?

Thank you again and best regards,
Kazuya Nakai.

Jason,

Can I ask you one additional question?
I know TPS568215 is a different deveice completely from TPS56428. But TPS568215 datasheet says the hiccup time is 7ms on page 18. I think 7us hiccup time might be too short to avoid the device damage. Could I ask you whether 7us is correct as the interval time of hiccup operation?

Thank you very much and best regards,
Kazuya Nakai.

Kazuya,
Check TPS56428 datasheet, there is no HICCUP time in datasheet. In family datasheet TPS56628, show HICCUP is 12ms.(you can refer this value)
Another, 7 us(typical) is a delay tiem: from Vout UVLO to enter HICCUP. (VOUT UVLO is lower than 65% target voltage)
