Part Number: LM3414 Other Parts Discussed in Thread: TPS92640 Hi Sir,
Looks different vendors have same variable frequency control buck topology LED driver compare LM3414 and one thing different is current sense design on high and low side.
Could you…
Part Number: LM3414 Tool/software: WEBENCH® Design Tools I trying to simulate LM3414 on Webench below condition.
But LM3414 was not appear selection list and list of "Show why other parts were not found".
Is there any bug on Webench?
Or, what…
Part Number: LM3414 Other Parts Discussed in Thread: LM3409 , TPS92515 Hello ,
i am using LM3414 for LED string (4 LED in series ) driver . Power supply 18~ 24V . LED VF = 2.82 V/ LED
please see attached schematics . when switch B closed (2LED in CIRC…
Part Number: LM3414HV Hi.
I used LM3414HV for LED driver. I used 9W RGB LEDx3.
But it makes faint light when turn off the LED.
Supply voltage is 12V and LX voltage is 5.3V(blue) / 6.18V(green) / 7.62V(red). I think this LV voltage is too low.
Why happened…
Part Number: LM3414 Hi Folks, I am using LM3414 as CC for 34W dimmable led driver. I want to measure the current at different brightness levels and will interface it with microcontroller. My question is, how can i measure the current between LM3414 and…
Part Number: LM3414HV Other Parts Discussed in Thread: TPS92512 Tool/software: WEBENCH® Design Tools We are currently using the LM3414HV part in our system. It works very well with our proprietary duty cycle LED dimming algorithms. This is great but we…

Part Number: LM3414 Hi
In designing LM3414 for LED lighting design, there will be EMC problems.
In product applications, the input is 36V, the output is 24V, single string 6 LEDs, the current range is 0.35A~0.7A.
The operating frequency is below 10KHz…
