Hello Ilya,
You can put a cap at that location but then you need an inductor too. Here is the schematic of the Sepic EVM. You will have to go through the design equations for the sepic, they will be different then the boost converter.
I would just…
Part Number: LM3410XSDSEPEV Other Parts Discussed in Thread: LM3410 Hi team,
My customer is evaluating LM3410 in SEPIC configuration to power an LED at Vf=3.1V and Vin between 3V to 4.2V. They see an efficiency of only 73%/74%. Can do you have suggestions…
Hello Kevin,
The inductors on both EVMs are rated for high enough current so you should only need to change the current sense resistor.
However, keep two things in mind: First of all the EVMs may not be designed for the increased heat generated. They…
Hello Jonathan,
You are correct. The datasheet should have the dots. You can see the correct connection in the EVM schematic.

Hello
Thank you for clear explanation, unfortunately i not have experience to work with LED drive and your clear answer very help me !!!
1. in order to privet misunderstood:
You add additional Indicator L2 in LM3410XSDSEPEV because Vout can be low…
If I were you I would look at the LM3410-Q1 https://www.ti.com/product/LM3410 . This is a boost/sepic converter that generates a constant current and is more efficient then the boost followed with a linear driver. It is only one channel but you could…
Hello,
So, you're going to have to narrow down what you are actually testing.
I see the inductor value as being 4.7 uH or 10 uH but the schematic shows 3.3 uH, which is it?
I also see Vin at 5V, 4V and 3.3V on the schematic, which is it?
Is the…
Hi yusuke,

Please refer to the "AN-1775 LM3410X SEPIC 6-Pin LLP Demo Board" to drive 1 single LED. schematic is below
Concerning possible Dimming ratio for LM3410 see figure below from datasheet…
