• LTC3779

    I have a application for LTC3779 switch. for the freewheel switch and boost rectifier, Can I use diode instead?

    if it can not be replace, please let me know why.

    Best regards

  • LTC3779应用

    LTC3779应用,DATASHEET 里面计算电感量和他里面的设计实例怎么不相符啊?我有个案子是6-100V输入,输出18-36V任何一个值都可以,输出功率350W. 我的电感和MOSfet该如何选择?

  • LTC3779 Switching jitter

    HI,

    I'm using the LTC3779 in boost mode, Vin 18-36V and Vout 40V.

    When the input voltage is around 33V-36V there is a noticeable jitter in the switching measurement (and also a loud sound) .

    At higher voltages than 36V the problem disappears.

    The switching…

  • LTC3779 buck inductance 

    Dear Specialist,

            LT3779 spec page 24 describes the buck inductance follows,

    and the example shows on page 34 is as below, if calculate with below figures, the inductance should be 1500uh rather than 15uh, can you help to check what's the problem…

  • LTC3779 Schematic for review

    Hi,

    Can any one help me to review the LTC3779 schematic with 300VDC input 14/8A DC output? Please note that, the VIN of the LTC3779 is limited to 136V.  PDF

    Thanks and regards,

  • LTC3779 BUCK DESIGN

    Hi

    • I'll try to design buck boost converter with LTC3779.
    • Input voltage is from 100V to 140Vdc and Output is 110Vdc 300Amps
    • Is it possible to run it at 10Khz or 15Khz for IGBT?
    • Or any other recommendation for big buck boost converter?

  • LTC3779 Buck Design

    Hi,

    We have been working on a high voltage switching power supply design that needs to take 140V and step it down to 48V with infrequent bursts of current around 1A but normally drawing a few mA. We chose the LTC3779 as it has an example in its datasheet…

  • need LTC3779 design support

    Hi

    I need to design a 10-13V input and 12V/50+A output module using LTC3779, I have some questions below.

    1. how I could sync 2 chips using PLL in ? is there is any reference design could provide ?

    2. what I could do if I try to use more than 2 chips…
