Part Number: LM25149-Q1 Tool/software: Hi Team,
Looking at the LM25149-Q1 datasheet, the stated overcurrent Vcs-th threshold tolerance is 49mV min to 73mV max. In the Typical characteristics section Figure 7-18 shows the Current sense threshold vs temperature…

Hi,
I want to disable the AEF, just to compare the EMI measurement results. I am trying to do it by connecting a jumper pin between CNFG and GND AFTER startup. But it does not seem to work. What am I missing?
EDIT…

I am trying to simulated LM25149-Q using WEBbench tool but it is showing the "simulation not enabled for this design". So, please let me…
Part Number: LM25149-Q1 Tool/software: Hi,
I have a few questions regarding the LM25149-Q1.
Is DRSS disabled by placing a 24,9k or 29,9k ohm resistor at CNFG? The application examples in the datasheet show a 24,9k ohm resistor and the table of configuration…

Part Number: LM25149-Q1 Tool/software: Hi,
The datasheet for LM25149Q-1 shows two typical applications. One for 2.1 MHz switching frequency and one for 440 kHz. Cinc is grounded using two different ground references for the two designs. Cinc in the 2.1…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Hi team,
My customer used our LM25149, and find the output result of our official calculator cannot match with the manual calculation result.
Could you please help double-check it? The calculator…
Part Number: LM25149-Q1 Hi support team,
The current value set by the sense resistor is considered to flow to the high-side FET.
How does a low-side FET get involved?
What is the current rating required for a low-side FET? Please let me know.
Thanks.
