Part Number: LM3409HV Tool/software: I AM TRYING TO BUILD A 200WATT LED DRIVER USING LM3409HV
INPUT 61VDC OUTPUT REQUIRED 52.8 VOLTS 3.8 AMPS
PWM FREQUENCY 40KHZ
CAN SOME ONE GUIDE ME REGARDING THE DESIGN PARAMETERS WHAT SHOULD BE Fsw RIPPLE CURRENT…
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…
Part Number: LM3409HV Hi,
I am looking for a table to calculate the LM3409HV at 48 V input voltage. I have the spreadsheet with the two off timers, but it seems that it gives wrong results when using only the standard circuit with one off timer and optional…
Part Number: LM3409HV Hi,
I'm designing an led driver to power a 0.75A 41.5V led board.
I've tryed to use the datasheet and the examples provided but I'm not sure about some components, expecially L1 and R sense.
On my protoboard I've used…
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 Hello,
Please check my design about LM3409HV?
The application is Heliport LED Driver.
LED module consist 5 series and 5 parallel. Each LED Vf is 3V and I want to driver it 350mA to 1A. (CREE/ XPGDWT-U1-0000-00E5E)
(But It will used…
Part Number: LM3409HV Other Parts Discussed in Thread: LM3409 , Good day, we faced an issue with a LED driver design that we made for tests. After the power is connected to the board, the LM3409 chip burns off. We looked closely at the chip and it seems…
