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 Other Parts Discussed in Thread: LM3409 Tool/software: This device has two operation modes: CCM and DCM. What are the conditions to transition from CCM to DCM?
Part Number: LM3409HV Tool/software: Hi TI Experts,
I am using the LM3409HV to design a 6A LED driver. Due to thermal concerns, I am considering using 2 or 3 MOSFETs in parallel.
My main question is: How many MOSFETs in parallel can the LM3409HV drive…
Part Number: LM3409HV Tool/software: Hi everyone,
I am using the LM3409HV driver to control LED current. The system generally works fine, but I am encountering an issue when I attempt to adjust the PWM signal (either increasing or decreasing the duty…
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 18uH…
