• LT4320

    I am planning on trialling the use of LT4320.

    In the data sheet it discusses the use of a 1uF ceramic capacitor and an additional electrolytic capacitor.
    From the data…

  • LT4320 - alternative supply

    Hi All

    I don't have this IC so I have a question if LT4320 will work properly when it's powered from half of the rectified supply.

    Nominal AC voltage is 42V ±30%.

    See attached LTSpice file.

  • LT4320 Voltage Range


    It seems this is a relatively basic question but does the LT4320/LT4321 operate down to 12VAC?



  • LT4320 Voltage Range


    May i know what is the maximum AC range of LT4320? 

    Based on the typical application of this part the LT4320 is mainly design in 24V AC and line to line of 48v RMS voltage circuit design. 

    So i would need to double confirm on this case. 

    Thank you…

  • LT4320 Minimum Voltage

    The LT4320 datasheet summary says it is good for 72V AC, yet the absolute maximum rating table of the input pins says a minimum of -3V.  I am confused?

  • LT4320 when using RDSON small


    I would like to use LT4320.

    So, I have a question.

    #1   When DC voltage 24 V is inserted and IAVG is set to 1 A, it is necessary to use RDSON with 30 mΩ or more.         

           However, is there a disadvantage when using it at 30 mΩ or less?

    #2   Is there…

  • LT4320 implementation with LT4293


    The DC2911A carries LT4321 ideal diode bridge (for 2 lines). Our customer tried to use 2x LT4320 instead of LT4321 with LT4293 and it was not successful. Is there any restriction to use an ideal diode bridge for such application and utilize only LT4321…

  • LT4320 CHarge Pump Frequency

    There is a mention of an internal charge pump within the LT4320 internal controller.

    But there is no further details on that.

    Would it be possible to disclose what frequency the charge pump is working at ?

    And how much of residuals at that frequency is…

  • LT4320 with center tapped Transformer

    Hi everyone,

    I´m wondering if the LT4320 is able to handle with symmetric power rails. I designed the following schematic and build the circuit but as soon I connect the 0V (center tap) rail from the Transformer to the circuit GND, I get high current…

  • LT4320-1 High Power Application

    Hi there,

    We are planning to use LT4320-1 for a 400 Hz three phase AC input to 28V DC output, 11 kW Ideal Rectification application. At full load the current going through MOSFET will be around 430A. The design will be based on DC2465A Demo card schematic…
