Part Number: LM3410XBSTOVPEV Tool/software: Hi everyone,
I am designing an LED driver using the LM3410X. My application involves a MIPI DSI display with a backlight consisting of 6 LEDs in parallel. Each LED has a forward voltage ( Vf ) of 6V and consumes…
Part Number: LM3410XBSTOVPEV Hello,
I am interested in your LM3410XBSTOVPEV/NOPB demo board. In its User’s Guide (AN-1996), Figure 8, it states “The evaluation board can be modified to allow the user to derive the power from an input supply that is…
Part Number: LM3410XBSTOVPEV Hello,
We would like to modify from this design. Could you please provide design files of this eval board?
Thank you very much,
Hi,
In the the app note for the kit says minimum 3.3V input voltage. I'm not sure why this is the case. The IC is rated down to 2.7 V and it should easily deliver the 190 mA at 14 V all the way down to 2.7 V. Not sure why the 3.3 V limit is stated…
thanks Clinton- after i thought about it (and added series LEDs to verify) it seemed clear output voltage needed to be higher. interesting (a little), and verifying your explanation, was 2 LEDs allowed the board to regulate properly but with DIMM=0 there…
Hi Dan,
Increasing the input and output capacitors probably won't make much difference efficiency wise. You can try doubling them as see. It just depends on how much is being lost in the resistive portions of the circuit (RMS losses). Average losses…
Other Parts Discussed in Thread: LM3410XBSTOVPEV The evaluation circuit LM3410XBSTOVPEV/NOPB (eval for LM3410x) has an input voltage range specified to be 3.3V to 5.5V. The LM3410x has an acceptable range of 2.7 to 5.5V. I'd like to understand the low…
Part Number: LM3410XSDSEPEV Other Parts Discussed in Thread: LM3410XBSTOVPEV Hello,
Besides the sense resistor, what else needs to change on the LM3410XSDSEPEV/NOPB or the LM3410XBSTOVPEV/NOPB evaluation kits to support 400mA and 800mA currents?
…
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…
Other Parts Discussed in Thread: LM3410XBSTOVPEV , LM3410 Hi,
My customer is evaluating LM3410 on EVM (LM3410XBSTOVPEV) and troubled by audible noise.
Could you tell countermeasure and what we should confirm?
Condition are followings;
- Noise…
