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…
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.
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…
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 you…

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
