Part Number: LM5013-Q1EVM Other Parts Discussed in Thread: LM5013-Q1 , LM5013 Greetings,
The switching waveform generated by the LM5013 IC on the LM5013-Q1 EVM appears as in the pic below.
The datasheet (of LM5013) mentions that Constant on-time control…
Hi Ricardo,
What can of noise do you see? Also, send some measurements if possible. RON really may influence or not the noise but we need to deep dive into it. Also, references your schematic and design to the document.
Thanks. snvu754a.pdf
Hello Nitya,
I input the values in the excel ss and some components are different from the ones I use. I copied the schematic exactly from the LM5013-Q1EVM evaluation board datasheet. I use 1mohm Ruv1 and 330k Ruv2, also Ra of 453Kohm. The Excel SS…
Hi Santosh,
1. Yes, the recommended table is a bit different than the abs max table. If one wants to, then you can set Ton to 2550nS, but it's not recommended. This is a bit different than exceeding the abs max for the device (for example exposing it…
Hello,
The waveform you show demonstrates insufficient ripple injection.
The SW waveform shows irregular pulsing which is a characteristic of this behavior...the the comparator is false-tripping due to insufficient in-phase injection voltage ripple…
Hello,
I suspect that the output will closely follow the input in the dropout condition you've described but I'll confirm with the engineer responsible.
I don't have insight into when the higher quantities will be available but we do have EVMs in…
