Part Number: LM3406HV Other Parts Discussed in Thread: LM3406 Hello Team,
I use the LM3406HV for dimming a LED CHain of 12 High Power LEDs. The Input Voltage is DC48V.
When I connect the VIN Pin to the Power Supply, the LEDs lights at full power. After…
Part Number: LM3406HV-Q1 Other Parts Discussed in Thread: LM3406 Hi expert,
There are two design examples in LM3406HV-Q1 datasheet, but I cannot understand where Ron and Ton values come out.
Please make sure which equation are Ron, Fsw, Ton induced from…
Part Number: LM3406HV Dear TI Support,
I am testing AN-1993 LM3406HV Evaluation Board with 2 Wire Dimming ( SNVA407B) and it seems not to work as constant current. The current is changing with LEDs number (load) and output voltage seems to be stable which…
Other Parts Discussed in Thread: LM3406HV Hello, Everybody.
I designed LED Driver with LM3406HV, Input voltage 48V, the output voltage 45V, and out current 750mA But this circuit doesn't work. it generates the output voltage 10V. What's the mistake?…
Part Number: LM3406HV Other Parts Discussed in Thread: LM3406 hi, there,
I am trying to do Pspice simulation using this LM3406HV chip in OrCAD, I can only find the LM3406 transient PSpice model (.lib file), the simulation can not run to the voltage I…
Part Number: LM3406HV-Q1 Other Parts Discussed in Thread: LM3406 Hi! I'm working in a project for agricultural applications using a 50[w] led with Vf=31[V] 1.5[A]. I decided to use the LM3406 because it's high input voltage range, dimming capabilities…

Other Parts Discussed in Thread: LM3406 I am investigating the efficiency of the driver LM3406HV.
I am working with a demo board ( http://www.ti.com/lit/ug/snva407b/snva407b.pdf ).
I am feeding 4 red LED with 0.356 A DC and 25 V. Each LED exhibits 2V voltage…
Other Parts Discussed in Thread: LM3406HV Good afternoon,
is it possible to use the LM3406HV as depicted in the figure below or it may damage the inductor?
The purpose is to feed each LEDs string for one third of the overall period, therefore the current…
