Part Number: LM5143-Q1EVM-2100 Hi Team,
A title, if I want to set EVM config to single output, two phase. Should I modify the red connection only? If there is any part that I need to modify, please let me know. Thank you.
Roy
Part Number: LM5143-Q1EVM-2100 Hi team,
I modifed the EVM board to single output mode, and connected DITH to VDDA in order to disable the dither feature.
I powered up the EVM board with Vin 30V and heavy load(10A), but the SW waveform from 2 phases seems…
Part Number: LM5143-Q1EVM-2100 Hi team,
Could you give me comment on following customer questions? They ask parameters related to R15 (49.9Ohm), R16(0Ohm), and C43(33pF) in the EVM.
Q1. What function does this circuit have?
Q2. What is the case that this…
Part Number: LM5148 Other Parts Discussed in Thread: LM25149-Q1EVM-2100 , LM5149-Q1 , LM5149-Q1EVM-400 Hello,
I am currently in the process of constructing a buck converter with the following specifications:
Input Voltage: 15-80V
Output Voltage: 12.51V …
KB,
Hi KB, are you referring to the datasheet image?
The LM5148 is the same DC/DC controller as LM5149, where LM5149 uses Active EMI filtering in place of the NC pins.
However without active emi filter the devices are the same.
That datasheet references…
Part Number: LM5143-Q1EVM-2100 Hi all,
Can you tell me how to make 6-phase operation DCDC converter using 3 EVMs? Do I need an extra oscillator input? If you have any schematics or documents, can you share that?
Regards, RYO
Hi Lei,
What does your schematic and layout look like? Did you route the current sense signals internally and away from noise sources?
Are you able to add a current sense filter?

Let me know…
Hello David,
I wanted to clarify my inquiry regarding the control circuitry and how the external components may vary based on different applications outlined in the datasheet. Are there any evaluation boards or reference design documents you would recommend…
Part Number: LM5143-Q1EVM-2100 Other Parts Discussed in Thread: LM5143-Q1 , LM5143 Hi,
I am using three LM5143-Q1 power supply IC's each operating at a switching frequency of Max-1MHz and Min-440KHz.
In an EVM(refer attachment) of LM5143 an EMI filter…
Mark,
It's fairly reasonable, even 2.2W could be a bit much, when comparing to the results from the default quickstart calculator.
By the way, the LM5149 quickstart calculator is meant to model the LM25149-Q1EVM-2100, and that EVM user guide has a…
