• LTC3105 & LTC3108 for thermoelectric generator

    Hello.

    I want to boot output voltage of thermoelectric generator (TEG).

    I had successfully used LTC3108 for voltage booster using low impedance peliter TEG.

    But the LTC3108 didn't work well, when I connected high impedance TEG.

    I saw some article…

  • RE: LTC3105 minimum power required for startup

    Hi,

    Ultimately I am trying to understand what triggers startup because I want to make sure I'm sizing my parts properly and I'm afraid of getting partly through a startup condition and getting stuck.  I have observed a partial startup condition…

  • Required minimum input amperage on LTC3105

    Hi guys,

    First time poster here.

    I am working on an invention that havests low renewable energy to slowly charge a rechargeable button cell and I am interested in using the LTC3105 to boost the ouput.

    Does anyone know the minimum mA required for the circuit…

  • LTC3105能量收集TEG

    按照参考电路,利用LTC3105搭建Thermoelectric Generator to 2.4V Super Capacitor Charger,输出电压非常小,不会上升到2.4V。发现上电测试R1R2的阻值与标称值不符合,大概为0.4M左右,但是将电阻取下再测阻值又是正确的。LDO管脚给了2.2V的工作电压,接入TEGVin输入大概为300mV左右,满足250mV启动要求,SHDN管脚做悬空处理。PCB走线也应该没什么问题呀!

    LTSPICE对电路进行模拟,发现LDO管脚加…

  • RE: Selecting LTC3105 for energy harvesting from solar cell

    Hi John, 

    LTC3105 can step up with a low Vin of 0.5V to 4.2V Vout however 100mA of load might not be possible. Most of our energy harvesting parts are meant for low power applications. If you could make series of solar cells as input (>0.85V) then LTC3106…

  • RE: Alternative to ADP5091 with higher power handle capability.

    Hi,

    There maybe no well suitable part to contain all the function. LTC4121 is a 400mA buck charger for solar panel and LT3652 is a 2A buck charger.  LTC3105 is a 400mA boost charger. But those don't contain the primary battery management.

    BG,

  • RE: What is the max resistance for MPPC pin in LTC3105?

    I believe you asked questions about start-up of the LTC3105 in another EngineerZone thread. In order to answer this question we need to get more information. To start, we need to know what solar cells you are using, and we need a copy of your schematic…

  • RE: LTC3108 vs BQ25570 (from TI)

    There are several Energy Harvesting devices available from Analog Devices that are optimized for a variety of applications.  For solar cell applications where Vin is typically higher than 1-2V, the LTC3129, LTC3106, and/or the LTC3105 may be a better fit…
