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…
Part Number: LM25149 To decrease the dissipation in the LM25149 internal VCC regulator in our application, we need to supply 5V external bias to the LM25149 VCCX-pin. We are using precision enable with a resistive divider on the enable pin.
Section 8.3…

Part Number: LM25149LM25149 is a Buck converter with External power stage components.
Normally, for Buck converters with internal switch, the current limits of the internal mosfet defines the maximum current upto which the converter can be used.
And…
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.
…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Hi team,
The LM25149-Q1 data sheet lists a Enable voltage rising threshold(VEN-HIGH) of 1.0V (typical).
Is there the Enable voltage falling threshold value(–40 to 150 degree)? Is it…
