Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 , LM25148
Tool/software:
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 Other Parts Discussed in Thread: LM5177 Tool/software: Hi,
My system requires an input voltage range of 7-18V and an output voltage range of 15-28V. I need to be able to set the output current to a fixed 3A. I should be able to…
Part Number: LM25149 Tool/software: When designing a circuit using the LM25149, I would like to switch the AEF and DRSS functions ON/OFF with a switch to evaluate the EMI countermeasure function.
I would like to know the optimal circuit configuration…
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-Q1EVM-2100 Tool/software: Hi team,
I used Bode100 to test frequency response of EVM. Vin=18V, 8A-resistive load, and the phase starts from -10° and reach 80° at cross frequency, which is only 29kHz.
Could you help explain…
Part Number: LM25149 Hi team,
could you pls help to review the attached image and then share more details about the voltage railing , how can we understand this in Chinese, from my side, i think this railing like a swing cause by the amplifier & input…
Part Number: LM25149 Other Parts Discussed in Thread: CSD17577Q5A , Tool/software: Hello,
we have a problem with LM25149 mosfet design - we are using a 24 V input voltage and we are currently outputting 5.3 V. For load we are using 3x parallel resistor…
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…
