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-Q1 Other Parts Discussed in Thread: LM25148-Q1 , Tool/software: Hi,
I'd like to go as low as 200 kHz (switching frequency). 5 V, 2 A output. I do not have any specific requirments when it comes to peak-to-peak current and such. What…
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: TINA-TI , LM61480-Q1 , LM5175 , LM5176 , LM5177 Tool/software: HI everyone,
We are using a delta 450 W brick which will convert 48 V to 24 V, 16 A. After this the following requirements to meet,
1. …
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…
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,
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 Other Parts Discussed in Thread: LM25149 Hi team,
Do we have min and max "HO(LO) peak source current" and "HO(LO) peak sink current" value for LM25149?
Cause I only see there is typical value on datasheet. Please…
Part Number: LM25149-Q1 Other Parts Discussed in Thread: LM25149 Hi team,
Do we have min deadtime value for LM25149?
Cause I only see there is typical value on datasheet.

Part Number: LM25149-Q1 Hi team,
The LM25149-Q1 data sheet lists a standby current (no-switching) of 124uA (typical).
Is there a reference value for the MAX value of the characteristic value(–40 to 150 degree)? For example, it is OK if you look at…
