Part Number: LM3409HV Tool/software: Hi,
We are use the LM3409HV for the LED driver, the output current is 3.5A max.,
Now, the LED are turn on when the power on, and the LED will be turn off after 10mins, and we pull down the EN about 10s, the LEDs…
Part Number: LM3409HV Tool/software: Hello,
I am writing in order to have a clarification. Why does datasheet reports 5A as maximum current for load leds?
Since this is a buck controller i can choose external components with carachteristics compatible…
Part Number: LM3409HV-Q1 I am designing a high-power LED driver using the LM3409HVMY buck controller with a 12V DC input to drive a single LED (current target 2A, VF =1.8V). Despite several hardware adjustments, I am only seeing a few mA of output current…
Part Number: LM3409HV Hi All,
I'm currently building a led driver based on LM3409HV.
In my test I've seen that using 1uF (for test I'm using cheap electrolytic cap) on output will solve noise problems.
Which cap should I use? I'm looking for an…
Part Number: LM3409HV Other Parts Discussed in Thread: LM3409 , Tool/software: I am working on a design for an LED Driver using the LM3409HV. The input voltage is 48V and the board is required to drive different LED strings from 3.5A, to 4.5A maximum…
