• Absolute maximum voltage of Boost-SW of LTC3633A-2


    Is it correct that is absolute maximum voltage of Boost-SW voltage.
    I confirmed INTVcc voltage that is between 3.1V to 3.5V on datasheet. I also confirmed nearly 3.6V at Boost-SW voltage on board .
    It may think that reason of capacitor between Boost…

  • LTC3633A/LTC3633A-1 datasheet spec conflict

    Hi , 

    In the DS of LTC3633A/LTC3633A table on page 3 declares the value of VIN1 to be in the range of 3V to 20V , whereas the figure on page1 under "Typical applications" declares it in the range 6V to 20V . Which one is correct ?


  • LTC3633A-1 Efficiency

    The datasheet doesn't show much on higher output voltages. I am using an input voltage on 12V and an output of 8.5V at 2.7A on SW2 and an output of 5.5V at 2.7A. I wants see the efficiency  curve on it but didn't see any information on it or recommended…

  • LTC3633A output regulation problem

    I'm working with an existing circuit design that has successfully used an LTC3633A dual switching converter for the last 3+ years.  Our most recent board build is having problems with one of the converter outputs, and I'm having trouble identifying…

  • 关于在LT4363-2及LTC4364-2中的Retry Duty Cycle问题?


    在选择使用LT4363-2及LTC4364-2中有一个参数Retry Duty Cycle;

    关于Retry Duty Cycle,我的理解是:


    Retry Duty Cycle=T1/(T1+Tcool) * 100%

    LT4363-2:Less Than 1% Retry Duty Cycle During Faults, LT4363-2;

    LTC4364-2:0.1% Retry Duty Cycle…

  • Pluto - 2 Rx and 2 Tx using MATLAB


    I would like to setup the SDR Pluto to operate in 2 Tx and 2 Rx mode.

    I have followed the steps in the following video : https://www.youtube.com/watch?v=ph0Kv4SgSuI

    However, I am unsure how to setup and control the 2nd transmitter or receiver. 

  • LTC3633A output coupling switching noise

    Hi all,

    Our customer will be going to select power IC, mult ch output.
    They will be concerned the output coupling, and switching noise.

  • RE: ADA4940-2, issue on creating 2 differential signals around 0V


    With a bit late, thanks for this suggestion.

    By applying -0.2V to R3, this circuits can convert 0 to 0.4V to a balanced -0.2 to 0.2V .

    It has been checked on the eval board.

  • LTC3300-2

    Hello everyone,

    I want to realize a communication between an LTC6804-2 and LTC3300-2 using the SPI that the first IC can generate.

    The problem is that the LTC3300-2 do not respond to the command I send to it, in particular I tried to send a 'Readback…
