Other Parts Discussed in Thread: TPS650250, , TPS25980
Hi,
I am using TPS650250 in my design for 12V to 5V conversion. I will be connecting load across 5V. My load is SATA HDD. I will be connecting 3 SATA HDDs where each can consume maximum of 1.5A. But when I hotplug two SATA HDDs at the same time, my 5V output would fluctuate i.e my 5V regulator would turnoff and On within few milliseconds. This was due to the sudden inrush current
We are going for R2.0 revision of the board and take care all these issues. Hence eFuse TPS25982 was suggested by TI expert. Can you please let me know TPS25982 will help me in solving this issue.
1. Let me know which is the part that i should select. Current limiter or current breaker part
2. Whether i should remove 5V regulator and use eFuse as alternate for that regulator?
3. Or I should connect the output from this 5V regulator as input to efuse and connect output of efuseto my SATA HDD?
3. Is it possible to give input of 5V and output of 5V
