Part Number: LM5148-LM25148DESIGN-CALC Other Parts Discussed in Thread: LM5148 Hi,TI
We use LM5148RGYR and LM74810QDRRRQ1 to implement our pre-regulator.
We would like to request a design review and get some feedback from your team. Could you please…
Part Number: LM5148-LM25148DESIGN-CALC Other Parts Discussed in Thread: LM5148 , LMG708B0 Hi all,
I'm designing a 48V input(35V-60V Li-Ion swing), 12V output Buck converter using the LM5148. The load current is also wide, meant to accept up to 20A,…
Part Number: LM5148-LM25148DESIGN-CALC Other Parts Discussed in Thread: LM5148 Tool/software: Hello guys,
One of my customer is designing a power supply using LM5148.
At this moment, they have the following question. Could you please give me your…
Part Number: LM5148-LM25148DESIGN-CALC Other Parts Discussed in Thread: LM5149 , LM5148 I would like to download LM5148-LM25148DESIGN-CALC, but visiting the download page does nothing. Could the document be uploaded here or the webpage fixed?
Part Number: LM5148-Q1 Other Parts Discussed in Thread: LM5148 , LM5149 Hello,
I'm currently using the LM5149-LM25149 Calculator for the LM5148 Buck Converter (as the LM5148 one's is not available).
For the buck inductance calcul, I followed the…
Part Number: LM5148 Hi,TI
The LM5148 datasheet mentions a typical dead time of about 20 ns.
However, on our custom board, the measured tDEAD2 is much larger than expected. This may cause unnecessary body diode conduction. Could you please confirm…
Hello Gareth,
At first glance it seems that your shunt resistance is too high for your application. and the output will be hitting overcurrent protection before reaching 12A.
To better understand the goals of the design, please fill out the…
Hi Bhavik.
Seems like you are hitting current limit here. Can you please fill in the design calculator for this device ( https://www.ti.com/tool/LM5148-LM25148DESIGN-CALC ) and share with me?
Thanks,
Best Regards,
Taru
