• LT3952 with Floating LED Output

    Hello LT Support,

    I am looking for an Eval board for the exact application like in the attachment. Or in the following link. https://www.led-professional.com/resources-1/articles/boost-buck-led-driver-topology-for-low-input-and-output-ripple-for…

  • LT3952 to power 450mA 42V LEDs with 4000:1 PWM

    Hi

    I am trying to design a LED driver circuit to drive string of two LEDs at 450mA and 42V (constant current - voltage is maximum from LED specs, in practice it is around 39-40V). The voltage on input is provided by 12V 6A power supply. I have used DC2361A…

  • LT3952 shutdown time in case of Input OV

    In the datasheet, there is no such time specified specifically that what is the maximum/minimum time required by the IC to shut down or foldback it's output in case of Input overvoltage or another shutdown situation is met. Request you to please help…

  • RE: LT8362 output shoots to maximum

    just realized.. i made a transposition error.. it's LT3952 what i am using. anyways.. i understood your point. thanks for the help DV. 

  • RE: driver for led

    Hi Lidas

    I used the requirements in your post to identify these potential products:

    LT3952,

    LT3478,

    LT3477

     

    Do these look suitable to your application?  Each has a demo board that you can find by visiting the specific product page for the part (URL…

  • RE: LT3952A PWM Dimming

    We followed the Buck topology using the LT3952 and build the circuitry. At 100% PWM, it seems no problem to the turn On the LED but when we start to input PWM duty cycle around 50%, the LED becomes very dim and not even drive at 50% of the full load.
