Part Number: LM5143-Q1EVM-2100 Other Parts Discussed in Thread: LM5143 Hi team,
In our LM5143EVM,there is a start-up characteristic showing as following:
With the Css=68nF setup, the calculated soft start time should be 1.94ms, but I am little confusing…
Part Number: LM5143-Q1EVM-2100 Other Parts Discussed in Thread: LM5143 , LM5143-Q1 , LM5117 Hi Team,
I need to check the dual phase interleaving performance of LM5143. Could you check the questions below?
1. LM5143-Q1 is populated in the EVM. Could…

Hi Team,
I modified the EVM and met some problem. Please see below image.
Sometimes, output =5V when I set Vout = 6.6V and I tried to re-power up the system and the Vout can be 6.6V.

Roy
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.

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…
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…
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
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…
Hello,
I do not have a 0.8V source in my possession. My design is identical to LM25149-Q1EVM-2100, but with components for 440 kHz switching frequency.
The datasheet says tie CNFG to GND to disable AEF. But I am still getting the same EMI results…
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…
