• RE: Any similar projects for Boost Converters?

    On behalf of Anthony Armstrong: 
    The Silent Switcher technology can also be applied in a boost mode topology. I am sure you know that with boost converters, the internal switching in a monolithic die can be very large – depending on how much output current…

  • LT3922 Buck Mode LED Driver

    Hello LT Support,



    I want to use the LT3922 in Buck Mode as an LED Driver for a 12V/1,5A LED (one power LED). The supply voltage is 15V. Additionally I want to use the SSFM option with up to 2MHz switching frequency (base fsw=1,6Mhz*125%).



  • RE: LT3518 Short-Circuit

    Hello Martin,

    The LT3518 is not designed for short-circuit protection.

    More recent ICs such as the LT3922, LT3795, LT3762, LT3932, LT8391A and other LED drivers now have the short-circuit protection which you are looking for.

    I hope this helps,


  • RE: LT3922-1使用BUCK的模式来驱动LED,是否也可以用到25000:1,

    这个片子是针对boost的应用的,只是通过改接电路构建成BUCK应用的,电压反馈要加level shift电路,所以器件多了一点,用在BUCK模式下,可以用到25000:1调光。

  • RE: .file_attr 1="1";

    Hi Gideon,

    Sorry for the delay in responding.

    The cause of the problem is "-file-attr CORE0" and "-DCORE0" both being included on the compiler command-line. Could you delete CORE0 from the "Additional attributes" in Tools Settings > CrossCore Blackfin…

  • Composite amplifier using ADA4637-1 and ADA4870-1

    I want to build a composite amplifier using the Figure 77 of the datasheet ADA4870-1. It says that the voltage offset is less than 500 uV. I simulate this circuit using LTSpice, when driving ada4637-1 with 0V and monitor the output of ADA4870-1, it is…

  • ADF7030-1


    I bought the ADF70301 - 433 EZKIT and I can't find, in the ADF70301 data sheet, the noise figure of the transceiver. 

    So I'm here to ask: how can i measure the noise figure of the ADF70301 using the 433EZKIT?

    Thank you for your support

    I'm requesting the gerber files for this product mentioned above... is it possible to receive them. thanks, 

  • LTC2439-1


    We wanna use the LTC2439-1 configured with 16-Channel Single-Ended Inputs, the Reference-Voltage is 5.0V and the Input-Channel Voltages are from 0-5.0V

    But the datasheet does not clearly describe the function for us with this configuration.

    We are not…

  • AD7988 - 1

    Good afternoon....

    I currently am using the above subject successfully in a design.  The power supplies are as follows: Vref = 2.5V, VDD = 2.5V and VIO = 2.7V - 3.6V.  Moving forward I would like to re-route the analog supply, VDD to track with VIO.  Can…
