Part Number: LM5140-Q1 Tool/software: The schematic I designed references the LM5140QRWGTQ1 schematic from SPRR462C, using BOM PROC101C(005). Please refer to my uploaded schematic for details. The current issue is: When EN2=High, the +5V output voltage…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: TMDS64EVM , Tool/software: Hi team,
The LM5140 on TMDS64EVM is breaking down.
VDDA and SS2 are working, but no pulse is being output from channel 2 side. I am turning the power on and off as…
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…
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…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: PMP15032 , LM5143A-Q1 , LM5143 , LM5137-Q1 Tool/software: dears,
My customer is planning to use LM5140 as a buck converter for the application: Vin=24V, Vout=5V (max current 40A), they will combine…
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 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 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?
BR…
Timothy Hegarty said: Hi Jerry,
Please send a completed LM5140-Q1 quickstart calculator for this design. You will need to increase the inductance if Fsw = 440kHz.
Btw, the 47pF cap should go from COMP to GND (not in parallel with Ccomp).
Regards…
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？
