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 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…
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: TPS92641 , , LM3409 Hello Jonard,
we now have a 11 channel driver with components on both sides.
Please take a look to the pictures and both pdf attached.
I calculted all parameter with the…

Part Number: LM3409HV Tool/software: Hi,
We use the LM3409HV for the LED Drivers, and now, we have below issue:
1. The circuit spec: The input voltage of LM3409HV is 40VDC, LED voltage is 32V, LED current is 3A, the inductance is 10uH;
Our issue…
Part Number: LM3409HV Other Parts Discussed in Thread: LM3409 According to LM3409 datasheet, we used standard circuit , our application is input voltage is 12V, the output LED lighting is 6V, the current is 1A, the Roff=8K, the Coff=470pF, L=100uH, Rsns…
Part Number: LM3409HV Hi,
I'm building a led driver based on the LM3409HV trying to replicate an aquarium led driver (based on the same IC)
My driver works fine except for the intensity adjustment at low PWM levels.
The original driver has a "moonlight…
