Part Number: LM5143-Q1EVM-2100
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,
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: 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, team
Do we have min and max deadtime value for LM25149? Cause I only see there is typical value on datasheet.
Part Number: LM25149-Q1EVM-2100 Other Parts Discussed in Thread: LM25149-Q1 Hi Team,
1. Do you have a reference schematic with dual-phase operation?
2. How to build a dual-phase board by modifying 2 LM25149-Q1 EVMs?
Thanks,

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…
