Part Number: LM5146DESIGN-CALC Other Parts Discussed in Thread: LM5146 , LM5146-Q1 Tool/software: For an input voltage of 28V to 60V, the output specs required are 12V, 8A output.
I calculated the compensation network based on the inductor (whose calculation…
Part Number: LM5146DESIGN-CALC Other Parts Discussed in Thread: LM5148-Q1 , LM5148 I want a buck converter with high input voltage range of atleast 48V and output for 5V ,3.8V ,12V with current rating of 5A ,2.5A respectively
Part Number: LM5146DESIGN-CALC Other Parts Discussed in Thread: LM5146 , LM25148 Tool/software: Hello,
i need a normal buck regulator (for example a LM5146) from Vin = 13V-17V to Vout = 12V. (4S Li-accu to 12V)
The special reqiurement is, that i need…
Part Number: LM5146DESIGN-CALC Hi,
I have the following doubt:
Scenario: Let us say, I need to design input filter (pi-filter) for a buck converter. The input switch side RMS current is 3A.
Now, let us say, after designing filter, I got a filter…
Part Number: LM5146DESIGN-CALC Other Parts Discussed in Thread: LM5146 Hi team,
my customer was seeing a spike in temperature of the device so we had recommended they change the Fsw.
they reduced it to 120kHz which helped. however, now they have…
Hi Nicole,
I recommend completing the quickstart to check your design https://www.ti.com/tool/LM5146DESIGN-CALC .
Not sure what's happening with your model - did you try running it with the default test bench?
By the way, I have a SIMPLIS…
Here is the quickstart tool folder https://www.ti.com/tool/LM5146DESIGN-CALC
PS: use the toff(min) spec in the EC table to derive the max duty cycle for a particular Fsw. The LM5146 does not have frequency foldback when max duty cycle is reached …
Here is the link to the quickstart calculator: https://www.ti.com/tool/LM5146DESIGN-CALC . It's always good to fill this out, as it provides a lot of insight into a particular design...in terms of component selection, bode plot, power losses, etc.
