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 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 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 a ripple…
Hi Nicolas,
I suspect you have huge inductor core loss and/or FET switching loss.
Send on a completed quickstart calculator file so we can examine the power losses: https://www.ti.com/tool/LM5146DESIGN-CALC
PS: given the max Vin of 58V, the LM5145…
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 capacitor…
Part Number: LM5146 Other Parts Discussed in Thread: , LM25145 , LM5145 , CSD18563Q5A Hi,
We need to use the LM5146 for our new design, and the parameter 36VDC input voltage, and output voltage is 28VDC and output current is 8A,
And now, we use the LM5146…

Be sure to tie SYNCIN to VCC or GND to configure FPWM or Diode emulation.
Hope this helps,
