• DC2456A (Demo board of LTC3779)设计文件打不开

    我下载了贵司官网的DC2456A的设计文件(https://www.analog.com/media/en/evaluation-documentation/evaluation-design-files/DC2456A.zip),但是解压之后却打不开相关的文件。

    我很想了解一下这一款的设计文件,请您试着打开一下,然后告诉我可以用哪些软件打开可以吗?

    压缩包里的.asc无法用LTspice打开,其他PCB文件也无法用AD打开。

  • 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…

  • LTC3779使用问题

    设计一个电源输入50-100V输出24V,空载情况下,在电源从50V慢慢增加到80V时,出现输出电压向上增加的情况电源输出异常,但再次降低电压,重启空载输出正常,一旦电压超过80V就出问题,不知道什么原因啊?

  • LTC3779 Vin=12V/24V, Vout=12V load regulation

    Dear Sir,

    When LTC3779 Vin=Vout=12V in different load, got different Vout values.

    Do you know how to fix Vout=12V±0.2%(max)? Or the accuracy should be how much %  ?

    Thanks.

    If Vin=12V

    Vo=12.05V at 10W

    Vo=11.90V at 100W

    Vo=11.70V at 200W

  • 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 - Min operating temp

    The LTC3779 has operating temperatures stated as between -40C and 150C but storage temps of -65C to 150C. Has there been any characterisation done to operating down at -55C and if so is there any data available ?
