Part Number: LM5013-Q1EVM Other Parts Discussed in Thread: LM5013-Q1 Dear TI Support Team,
I faced an issue with the LM5013-Q1 EVM. While testing the board under normal operating conditions (as per the EVM user guide), the IC burned immediately upon…
Part Number: LM5013-Q1EVM Other Parts Discussed in Thread: LM5013-Q1 HI,
I plan to use LM5013-Q1 Eval board along with my customized EMC filter. I would like to run LT spice simulation to measure the noise generated by this board and thereby use it…
Part Number: LM5013-Q1EVM We are using LM5013-Q1EVM input voltage 48V, Vout=12V and Iout=1.5A(at room temperature 24 °C) . Case temperature of IC and Inductor is ranging between 60-65 °C as per the details available in user manual(attached Below)

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…
