• Solar powered lithium charger with LTC3105 & LTC4071

    I would like to implement the lithium battery charger given at https://www.analog.com/en/design-center/reference-designs/circuit-collections/ltc3105-ltc4071-2-cell-solar-panel-li-ion-battery-charger.html#cc-overview.  Battery being charged is Li-Ion 3.7V…

  • Selecting LTC3105 for energy harvesting from solar cell

    Hi,

    This is John from Qmax Systems, 

    We are designing a product - energy harvesting from solar cell. Our application requires a boost converter to convert 0.5V to 4.2V with an output current of min 100 mA, Do you think LTC3105 will support this application…

  • LTC3105 on Demo Board DC2042A with solar cell

    Hello everybody,

    I purchased the DC2042A demo board, which is equipped with a LTC3105. It figured that I had to change it a bit, since it is meant to be used in a current loop setup. So I removed the very big capacitor C16 220µF and the diode D1. I then…

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

    I'm using LTC3105 as a trickle charger for a Li-Po battery as shown in the first page of the datasheet, but with a 1W, 5V rated PV panel instead of a single cell one. I'm using a 390k resistor in the MPPC pin because I want the panel to work at 3.9V …

  • LTC3105 Energy Harvester taking more current from input without any output load

    Hello sir,

          We are using LTC3105 Energy Harvester in one of project.

    We are giving input voltage to LTC3105 using Variable power supply

    We designed LTC3105 ouput to 4.3V

    I given input from 55 mV to 450 mV

    We tested this LTC 3105 wtihout any output l…

  • ltc3105模拟仿真时如何控制输入的功率? 添加限流电路可行吗?

    如图,我在使用ltc3105模拟时,想知道在低于多少的功率时,该芯片将无法输出预计的电压,但是我是用恒压源或者恒流源时均无法控制输入的功率,所以我想知道有什么函数或者命令可以实现 控制输入功率 这一目的吗?

  • 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,

    K…

  • 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…
