Part Number: LM3404EVAL Other Parts Discussed in Thread: LM3402 Hello,
Working with the following schematic I have several questions. Thank you for your help. The below circuit was designed using TI LM3404xx-1-A data sheets SNVS465G and the AN-1839 LM3402…
Hi Mark,
The input voltage is determined by many factors such as output voltage/current, switching frequency, inductor.
Besides, for inductor, you should also pay attention to the saturation current beside inductor value, because over current leads to…

Hi team,
When the PCB with LM3404MR/NOPB is not installed and it is operated by a DC power supply and a function generator, it operates as designed, but when the board is installed in the product, Fsw decreases significantly. In this…
Part Number: LM3404 We are using LM3404 in one of the designs.
The Vin =12V, Vf =2.1V, No of led -2 If =1A.
I have a clarification regarding the Switching Frequency & Ron value. As per the datasheet page 9 figure 14 .
For a Vf of around 4V the Switching…
Part Number: LM3404 Hi everybody from Italy
As you can see in the linked messages -I'm tryng to drive a Cree COB led with the TI LM3404.
At the beginning I received help from Mr. Irvin and - thanks to this - I was able to realize an excel spreadsheet…
Part Number: LM3404 Other Parts Discussed in Thread: TPS92692 , LM3409 , TPS92515 Hi E2E,
Good day.
What is the contrast ratio of LM3404 and TPS92692? Can anyone of these parts achieve a minimum contrast ratio of 15,000, or 25,000 to 1? Regards, Carlo
Part Number: LM3404 Hi,
I have three questions regarding to LM3404.
1. How much is the minimum PWM dimming frequency of the LM3404?
2. How can we calculate PWM dimming resolution of the LM3404?
3. Lower PWM dimming frequency is better resolution than…
Part Number: LM3404 Good morning
I'm trying to design a driver for a CREE COB led and I'm wondering if LM3404 is suitable for this purpose or if you can suggest to me some more specific component.
I read attentively the LM3404 data sheet aveilable…
