I am using LM5145 in my board as 40V regulator. Input voltage is 48V. When input 48V, the board is overheating and so LM5145 has been damaged. I designed the circuit by using the…
Part Number: LM5145 Tool/software: hi I am working with LM5145 board. But my LM5145 board doesn't work properly. Input voltage is 48V and my design is 40V output.
But output is 0V and LM5145 IC is overheating.
Please review my schematic and help me…

Hello team,
What would be the max output power possible by LM5145? I know it will depend on external FETs, but is there any maximum power?
Also, the max IOUT of LM5145 is stated as 30A from TI.com. How was 30A decided?…
Part Number: LM5145-Q1 Other Parts Discussed in Thread: LM5145 , Tool/software: Hello support teams.
I would like to operate converters that use LM5145 in series.
Is series operation possible with LM5145?
I am concerned that if there is a difference…
Part Number: LM5145 Tool/software: Dear Texas Team,
We are planning to integrate the LM5145RGYR IC into our system and require a suitable simulation tool for evaluation purposes. Kindly share the relevant tool or resources at the earliest. We look forward…
Part Number: LM5145 Tool/software: Hello team,
What would be the total power consumption from LM5145 itself?
Is there any methods/equations to calculate it?
Best Regards, Kei Kuwahara
Hi Makel,
If Cout is 220uF/20mΩ plus 4 x 47uF ceramic, the total Cout is not 75uF. It is approximately 220uF + 4 x ~20uF = 300uF, and I would estimate the effective ESR at 5mΩ.
Here is a file to help estimate that-
