Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143 , Dear All,
Here are 2 outputs that I'm trying to achieve:
Output I
Input voltage: 46-54V
Output voltage: 12V +/-5%
TDP: 250W (30A)
OCP: 50A
Type: non isolated
Ambient: 60C
Cooling: ? …
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-Q1 , Hello TI,
Can be used LM5140Q1 IC when Vin is overlimit using by external gate driver and external startup supply?
Best Regards,
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143-Q1 , LM25149 , LM25148 Hi Team,
My requirement is showing as below.
8~21Vin, 3Vout, Iout 9A
We want to find 2-3phase buck controller to achieve the requirement because we want to lower down…
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?

Part Number: LM5140-Q1 Hi Support Team ,
Regarding LM5140, I would like to know the following questions:
My customer uses LM5140 to design products,
It is found that at 12V output, after the load is connected, the MOS tube is hot seriously and the inductance…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143-Q1 , Hi team,
Here is a confusing item about LM5140; LM5140 is a external switch buck controller.
Since MOS in this converter is external, so how to know the maximum output current of LM5140…
Part Number: LM5140-Q1 Other Parts Discussed in Thread: LM5143-Q1 , Hi
Due to the customer requirements like SoC sleep mode we would like to know the efficiency when LM5140Q1 under output 1mA condition, I have searched the datasheet and find the efficiency…
