Part Number: LM25149-Q1EVM-2100 Other Parts Discussed in Thread: LM25149-Q1 Hello Team,
Our customer want to evaluate dual phase operation by using 2pcs of LM25149-Q1 EVM but somehow they can't work well.
Can you please let me know the setup to perform…
Part Number: LM25149-Q1EVM-2100 Hi, team
when start up with heavy load(13A), see overshoot on Iout. Is it normal? and what can cause this overshoot? (such as test method?)
test condition: Vin=12V Vout=3.3V Iload=13A
Part Number: LM25149-Q1EVM-2100 Hi support team:
when system output 3.3V/1A, I tested output ripple is 280mv(output capacitor is 188uF ) in PFM mode.
I think this voltage ripple is too large, could you please tell me what is the ideal voltage ripple in this…
Part Number: LM5143-Q1EVM-2100 Other Parts Discussed in Thread: LM5143 Hello,
Could you advise how EN1/2 is only 1.2V even when VIN is applied with 12V in LM5143EVM?
I measure VIN and PGND, then see 12V. I measure EN1 and PGND, then see 1.2V. EVM used…
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…

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.
Regards,
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.
Roy

I am currently in the process of constructing a buck converter with the following specifications:
Input Voltage: 15-80V
Output Voltage: 12.51V …
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…
