• LTC3105 simulation

    Hello,

    I am trying to perform some simulations in LTspice using LTC3105 model. In order to do that, I have this model of a solar cell (Isc=24mA, Voc=4.1V, Vmpp=2.8V):

    LTC3105 is suposed to control the solar cell voltage in order to get maximum power…

  • LTC3105

    HI,

    I'm new here. I was planning to ask for a Field application Engineer to come and check this doubt with us, but let me give a try here.

    I have a circuit using the LTC3105 similar as last schematic page 14 of datasheet with some differences.

    I have…

  • LTC3105 conversion efficiency

    Hello Sir

    DC1587A7A tested
    The test conditions are as follows
    * Vin 0.6V

  • Parallel solar panels with LTC3105

    Is it possible to parallel solar cells for use with a single LTC3105? Something like below.

    A little background: The device is a cube, with solar panels mounted on each face. The idea is that in a given plane, only one of the panels will be illuminated…

  • 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 not regulating properly

    Hi,

    I am attempting to use the  LTC3105 to regulate 5.25V. I am using 4 solar cells in parallel as the power source. At the max power point of the solar cells, they are rated at 1.67V and approximately 18.4 mA (so for four in parallel, that would be approximately…

  • LTC3105 minimum power required for startup

    Hi,

    What is the minimum power required for startup for the LTC3105? The datasheet shows a minimum startup voltage of 0.25V typical (0.4V max), but gives no indication of current/power requirements to move from startup to normal operation. In fact I couldn…

  • 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…

  • 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…
