Other Parts Discussed in Thread: LM3464 Hi,
I've seen a LM3464 being referred to (or implied at least) as WEBENCH enabled. However I've not been able to get LM3464 in WEBENCH. Can someone confirm or deny that LM3464 should be in WEBENCH?
A bit…
Other Parts Discussed in Thread: LM3464 My customer is asking the following. Please review and let me know what you recommend. LM3464.pdf
Part 1:
I’m having some issues with dimming on this LM3464 driver.
I have thus far been unable to use PWM dimming…
I have a customer asking the following:
I have been playing with the eval board you got for me, and am having issues getting it running.
I’m trying to drive a single 12V LED @ 1A.
I replaced the current sense resistors with .22OHM resistors according…
Other Parts Discussed in Thread: LM3464 In LM3464 datasheet page no.10 under subsection Operation Principles of DHC, it is written that
when all the output channels are in regulation and the forward voltage of any LED string decreases due to temperature…
Other Parts Discussed in Thread: LM5021 , LM3464 We want to design LED Driver board using LM3464 + LM5021 combination along with a Microcontroller for a load range of 50W to 100W.
Can you share "Design guide" / "Design Appnote" of LM3464…
hello Neil
For LM3464, there are several protections including LED open, LED short, OVP. The device continuously monitors voltage of DRx, SEx, GDx to see if any fault is triggered. So to further figure out, is it available at your side to get the waveforms…
Other Parts Discussed in Thread: LM3464 , TL431 , LM3466 We are using a power supply with output 40V x 3A and we have problems to adjust the current in 4 channels.
Using only one channel we can adjust the current (700mA) and it stay stable, but when we increase…
Other Parts Discussed in Thread: LM3464 Is there is a way to manipulate the LM3464 to phase shift the gate driver outputs so that all 4 strings of LEDs are not turned on/off at the same time? This would help create a constant current draw, rather than…
Other Parts Discussed in Thread: LM3464 Hello everybody,
I am trying to design a led driver with lm3464 for street lighting. I need ac/dc power supply 100-150W, around 230V AC input and around 50V DC output. Does anybody know what is appropriate AC/DC…
Other Parts Discussed in Thread: LM3463 , LM3464 1) The DIM is to control all the LEDs. No option to DIM each LED separately. Correct?
2)Can we use with toal of 5A ?
