Hey guys,
I am using TPS84621 in my circuit.
I am facing the problem in negative temperature with this Module.
Whenever it goes to low temperature, the module is turning off.
My load current is 1A (Imax).

The schematic looks OK. Can you share some waveforms?
Can you take waveforms of Vin, Vout, INH and PH during normal operation and when it is shut down?
You can send them to me directly at jarrigo@ti.com.
Thanks, Jason
Sir,
Now i have added soft start capacitor (10000 pF) at SS pin of TPS84621.
I have connected the module to SPARTAN 6 FPGA. (LX150) (Vccint Supply)
In negative temperature, whenever i run the test cases related to that FPGA, It is turning off.
That is also only for first 2 times. Next time if i run the test, it is not failing.
I have load side capacitance (210 uF) preferred by SPARTAN 6 FPGA at the Vccint supply.
In negative temperature, i am taking the wave forms.
