• 3-phase PFC and LT8312

    We have a legacy power supply that has to be redesigned from the ground up. The input is 115 Volts, 400 Hz, four wire, three phase Wye connected. The desired output s a single DC voltage to feed downstream DC-DC converters, which will be designed separately…

  • RE: 3-Phase 4-wire in to 3-Phase 3 Wire

    Good Afternoon

    The ADE7878 can be configured to accept multiple different configurations including 3 phase 4 wire and 3 phase 3 wire wye and delta.  Our FAQ:  AN-639 that is available on our website has detailed diagrams of each connection on pages 12…

  • ADUC843BCPZ32-3


    咨询下单片机ADUC843BCPZ32-3 的技术问题:

    1.)参照DATASHEET, PSEN脚在代码执行模式下应该输出高,实际输出为低(0.005V左右)。


    3.) 代码运行过程中,PSEN管脚可否通过电阻上拉到电源?



  • Divider-by-3 duty cycle


    I need to use a divider-by-3 device in my product.

    It requires to output a signal with 50% D.C.

     Input is a 25-100MHz SE signal.

    Output is a divided-by-3 differential signal.

     Can you confirm the following:

    1. HMC794LP3E
      Datasheet states “Duty Cycle…
  • ADE7880 - 3 phase 3 wire delta configuration


    As per the ADE7880 datasheet pg. 43, in three phase three wire delta configuration, Phase B active, reactive and apparent powers are 0.

    So, I would like to know if there is a way to find out the Phase B power data in three wire delta configuration…

  • ADF4355-3

    In ADF4355-3  frequency synthesizer , 

    can  i use both RF outputs A and B at the same time ? 

    because iam using this IC to generate LO for two channels at the same time .

    what is the Rf output level of the both A and B at 4 GHz ? 

  • LTM2881IV-3

    1. When the thermal shutdown function is activated at 125, can the IC be back to its normal working condition when the temperature drops to some degree?
    2. For the over current protection function, will it shut down the IC? If yes, what is the maximum current…
