Part Number: LM5140-Q1 Hi,
Vin=12V Vout1=3.3V Vout2=5V
Since our outputs are 3.3V and 5V, we connected the FB pins as follows. But when we take measurements, we can't see 5V on the VDDA pin, so the outputs are not as we expected. What could be the reason…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143A-Q1
Our original design was based on using LM5140-Q1,
but TI has significantly increased the price of this IC
I would like to ask if we can use LM5143A-Q1 instead.
If it is a suitable replacement…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143 Hi,
The formula for lm5140 and lm5143 is different, I've seen both formulas in other places.
It looks like one is based on Q and one is based on W, but which is better?
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM25149-Q1 Hi TI engineer,
We found 3 boards’ load switch damage which is after LM5140 5V OUTPUT in our project. Each board has two load switch ,both damage. They are low impedance in IN pin…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM25143-Q1 , LM5143A-Q1 Hi Ti team,
We are checking all ICs in our BOM if they have any errata sheet, does LM5140-Q1 have any errata sheet?
Part Number: LM5140-Q1 Hi Team,
I'm using LM5140 DUAL Buck controller in my design.
The current requirement are: 25A@3.3V, 8A@5V.
The calculator tool shows the efficiency of the regulator drops above 20A current for 3.3V output.
Attached the values…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143 , Dear All,

Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143-Q1 hi,
I designed a power solution---24V input, 12V/20A and 5V/5A dual output, the design is below, about 12V output,
1.change current sense resistor from 0.004 to 0.002
2. change inductor…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143 hi,
what's the max output current LM5140-Q1 for 12V output/24V input? as we know, it has 2 output, Vout1 and Vout2, so can it output 50A current by parallizing the Vout1 and Vout2?
