Part Number: TPS25990 Other Parts Discussed in Thread: TPS25985 , Tool/software: Hi team,
May I know what's the short current threshold when it have one TPS25990 parallel with one TPS25985?
Does it count together? 158.8A + 290A = 448.8A ?
How it count…

Hi Expert,
In switch applications, the ambient temperature inside the chassis may be as high as 60°C. In this case, what is the recommended maximum RMS current? Is it reasonable to use RθJA = 19.9°C/W for evaluation…

Part Number: TPS25990 Other Parts Discussed in Thread: TPS25985 , Tool/software: I would like to get Thermal model of TPS25990 and TPS25985 for Thermal simulations.
PDML file or CTM file are needed.
Thanks!
Part Number: TPS25990 Tool/software: Hi
I would like to confirm Tss formula. The formula in the datasheet differs from the calculated value in the design tool.
The difference is 1,000 times. Thanks
eeeeeee
Hi David,
Looks like you will need to monitor current through pmbus registers and then control the EN pin of device based on current level.

Hi TI expert,
2 questions as below need your reply.
Q1. In real calculation, the power consumption seems far lower than 100mW, Why RIMON, RILIM, R1, R2 suggest use 0603(1/10W)?
May I use 0402 size (1/16W)?
(80A*18…
