Part Number: LM3409EVAL Other Parts Discussed in Thread: LM3409 , , AM4376 Tool/software: I am designing LM3409 in my new project.
I couldn't find any layout files for the LM3409EVAL board on TI website.
I did find the Gerber.
But I need layout…
Part Number: LM3409EVAL Other Parts Discussed in Thread: LM3409 Tool/software: Hi TI Team,
I am currently in need of an LED driver that can meet specific requirements. The driver should be capable of delivering a maximum output exceeding 1.0A and support…
Part Number: LM3409EVAL Other Parts Discussed in Thread: LM3409 For schematic design of LM3409, such as PDF document design, if the input is 24V and the output is 5V, how should the corresponding parameters be designed? Does VTURN-ON need to be configured…
Part Number: LM3409EVAL Other Parts Discussed in Thread: LM3409 Hello,
I'm trying to use the LM3409 eval kit to control the current through a peltier cooler (CUI part number CP85438). My Vin is 12V and I am using the analog adjustment pot to turn…
Part Number: LM3409EVAL Other Parts Discussed in Thread: LM3409HV , LM3409 Hi,
I modified an LM3409HV EVM, but it's not working as I would expected it to. The changes I made to the EVM are as follows:
L1=68uH (3.6A); Rsns = 82mR, Roff (R6) = 18.2kR…
Hi, so there are a few things. First I don't have access to the equipment right now, so I can't get the scope shot your requested. But I also don't see the need for none AC coupling. The reason I switched to AC coupling was because with DC coupling, the…

I'm trying to use the 3409 chip on its DEMO board, using EN for PWM. I am trying to drive single high-power LEDs. For instance 6A at 6V. I have beefed up the PMOS FET as well as the schottky…
Hello Irwin,
Yes, shunt dimming is what I want to use. The photodiode I was speaking is the equipment I use to monitor the load LEDs, it is not an optocoupler in the path of Q3 (the shunt MOSFET) but I didn't think about the delay it added. I measured…
