Part Number: LM5146-Q1 Other Parts Discussed in Thread: LM5146 , LM5145-Q1 , LM5145
Hello There,
I have tried to simulate LM5146 in Pspice. As per my design calculation I have programmed IC. But high side drive is not functioning.
Please…
Hi Denis,
The LM5146/-Q1 was specified slightly more conservatively than the LM5145/-Q1. Of course, it's the recommended operating range that is important, and the LM5146 goes to 100V. We now have a consolidated quickstart calculator for the LM5145…
Part Number: LM5145 Hi experts,
I have some confusion when I am learning the datasheet of lm5145.
Q1: How to understand the function of this circuit in red？(Page 16)
Q2:I want to know how output capacitance that meets dynamic characteristics is…
Part Number: LM5145 Other Parts Discussed in Thread: LM5137F-Q1 , LM5143A-Q1 Tool/software: Hi,
Noting the link ( https://www.ti.com/document-viewer/lit/html/SSZT900 ), is it possible to show/reproduce the schematics in greater detail please (specifically…
Hi Chase,
The LM5137-Q1 data sheet specifies this...the gate drive voltage is 5V.
If higher gate drive amplitude is needed, take a look at the LM5145 / LM5146 controller family where it is 7.5V (or higher if external VCC is available).
Regards…

Part Number: LM5145 Other Parts Discussed in Thread: LM5146-Q1-EVM12V , CSD18563Q5A , CSD18533Q5A , LM25137 Tool/software: Hello!
I am designing a voltage regulator using the LM5145. The input range is 15-52V, and the output is 12V at 10-12A. I have…
Part Number: LM5146-Q1-EVM12V Other Parts Discussed in Thread: LM5146-Q1 , LM5146 , LM5145 Tool/software: Hi,
I am trying to find how AGND and PGND are connected in LM5146-Q1 EVM.
When I see all the four layer in EVM user guide, I am not able to see…
See the LM5146 EVM https://www.ti.com/tool/LM5146-Q1-EVM12V , which is 12Vout, 8A, 400kHz and quite close to the customer's spec. The LM5146 is the same as the LM5145 but rated for 100V input instead of 75V.
