TPS544C25: TPS544C25 - power sequencing

Part Number:TPS544C25

Hello All,

I'm using multiple TPS544C25  devices and power sequencing it.

All the 4 units looks good but CH3, 1.2V rails looks that it oscillates for some time before getting to the the final rails.

The sequence is CH2, CH1, CH3, CH4

What would you recommend testing to debug it?

Thanks,
