Hello Team
We want to use LM25149-Q1 for Automotive controller power. We designed the circuit with information obtained using WEBENCH. We designed it to be able to…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Tool/software: LM25149 datasheet says external differential mode input filter size reduces by 50%. What it means... external EMI filter is needed?
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Tool/software: Datasheet says active EMI filter is disabled when load current is less than 30% of the current limit value. In my application i need a front-end converter to generate supply…
Part Number: LM25149-Q1
Tool/software:
For the design of buck converter from 24V to 5V, we just used LM25419. And we designed it for 8 Amps with 5mE sense resistor. But just after 0.5 Amps, the voltage starts dropping as a sawtooth wave even current too…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Tool/software: Hi team,
I am planning to use LM25149-Q1 in dual phase and connect 71.5kohm on primary IC and 90.9kohm on secondary IC.
As an automotive risk analysis, I am considering if…
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…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 , LM25148 , , LM25148-Q1 Tool/software: Hi everyone,
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 Hi Team We are planninng to use the LM25149-Q1 as a for 16.8V 5A CCCV Charger. I have the calculator and Webench design ready and i have a few doubts and the numbers are not matching on both the the quickstart tool and Webench. If…
