• LTC3890 & LTC4000 ITH pin connection

    Hey all,

    It's my first question on this platform and I hope somebody can help me with my problem. I have connected the LTC3890 with the LTC4000 to charge 4 Li-ion batteries. Before connecting the ITH pin both boards worked good. The ITH on the LTC3890…

  • LTC4000 & LTC3890 and the ITH pin

    I have connected LTC4000 with LTC3890 to create a UPS  with a Li-ion battery pack. I have problem that the pin ITH has always the value 0.4V. As a result the voltage out the converter (LTC3890) drops from installed value 21.3 to 16.1V. Also the converter…

  • LTC3890 Demo Board DC2236A modification not working

    Using the DC2236A board as reference, I narrowed the input voltage using the same LTC3890 part from 14V < VIN < 18V but run at a higher frequency of about 400Khz at max current 18A.

    using the available LTpowerCAD, I obtained those adjusted values…

  • RE: parallel LT8930A controller clock synchronization without external clock?

    Can clarify the ADI part number, there is no LT8930 product. Do you mean LT8390 or LTC3890?

  • RE: Inquiry regarding Antislope Compensation

    Hi

    The designer has to make choices as to what features can be incorporated on a certain size die with a given process and meet packaging and cost constraints. Antislope Compensation was not given priority over other requirements on LT3845 and LTC3890…

  • DC2236A-B

    Hey All,

    I am working on de DC2236A-B and i adjust it so its output voltage turn to be 22V. As a results was the chip LTC3890 three time broken. I replaced it but i am not sure any more if this board will give the needed voltage. The only thing I have…

  • RE: ADP1031

    Hi Mehmet,

    I'm afraid the ADP1031 is not capable of providing such output power.

    Do you need isolation for your application? If not, ADI have bunch of Buck controllers that I think can cater your requirement (non-isolated) like the LTC3890 or the LTC3892…

  • PWM solution proposed

    Master,

    Looking advise on ADI proposal. 

    I'm thinking of LTC3890 for Load B (18-24Vdc, Current 5-10A) 
    1. Isolated DCDC Converter, Input rated 24Vdc,300W; Output Voltage 18-24Vdc, Current 5-10A                                                                                  
    2. PWM Controller Module/Circuit, Input rated 24Vdc,30…

  • RE: Question about LTC7851

    Hello,

     

    The current sense inputs of the LTC7851 will need to be divided down to keep the voltage under their maximum rating. This may require precision resistors with a tolerance of 0.1% or better to minimize the common mode error due to resistor mis…
