TPS543C20: SCP SOA and Fsw tolerance

Hi~

We have some questions for TPS543C20.

1. Short circuit SOA

Here is SCP test waveform, how do I confirm the SOA of TPS543C20 is no problem with this short current?

P.S: 2 phases stackable application for SCP tests

2. What is the tolerance of switching frequency?

Datasheet does only mention typical value.

Thanks and Best regards,

Tiger
