• LT3956 unexpected current waveform

    I’m looking for insight into some problems I’m having regarding the current waveform of an LT3956 LED driver. The circuit is very similar to the buck-boost application from the datasheet (page 17). The screenshot below shows the application with the updated…

  • LCD Backlight Driver 14,3V @ 600mA with IC LT3956

    Hi, 

    I use LT3956 led driver for back light driver. LED driver will be work 9-36V supply voltage. My LED parameters are 14,3V @ 600mA. I try to simulate circuit but I can not find needed parameters.

    Could you please help me for this.

  • LT3956 CIN(Input Capacitor Selection)

    Would an arithmetic expression of a data seat be right?

    When the price is input and I Calculated, it won't be 4.7 μF(boost mode) ,(my calculation result is 10 μF )

    And buck mode,my calculation result is 11.75 μF

  • RE: LTC7840 & LT3795 LTPowerCAD File

    I just downloaded LTPowerCad and did a sync release, but I don't see the LT3795 in the list of supported parts - sorry about that because I do not think the LT3795 is supported in LTPowerCad.
