• LTC3331 using primary battery

    Hi

    I am considering the LTC3331.

    Is it okay to use a solar cell as the main power source and use a primary battery instead of a secondary battery as a spare?

    If it's okay to connect a primary battery to the LTC3331, where should I connect it?

    best…

  • PMIC using (LTC3331, DEMO CIRCUIT 2151A)

    Hi, I'm a graduate student and I am major in Energy harvesting.

    We are going use the PMIC (LTC 3331) to charge the commerical wearable devices.

    Since, our enery type is AC with high voltage(1 kV) low current (1 mA), so we need to rectifing it and…

  • Combining Sources with LTC3331

    Hello,

    I'm working on a project where I'm trying to combine light and piezoelectric energy harvesting. For this, I want to use LTC3331 as it is more configurable than the alternative LTC3106/LTC3588 parts in your portfolio. If you have other suggestions…

  • LTC3331

    你好,在用LTspice软件仿真时,设置的电池断开电压为2.7V,重连电压为3.05V,实际仿真过程中,设置VIN输入为0V,VOUT为3.3V,当BAT-IN输入电压为1.8V时,降压升压转换器已经开始工作,输出电压为3.3V,只是什么原因呢

  • Using LTC3331 without backup battery

    Hello,

    I am designing the LTC3331 for  piezoelectric energy harvesting. I am not using the back-up battery feature that is why I am asking if there would be any problem if I left the SWA and SWB pins floating.

    Thank you in advance.

  • RE: ltc3331

    Make sure you are within the programmed UVLO window. For the widest range (just to get you started, you might use UV3-UV0 = 1111).

    I might also recommend adding some series input resistance so the LTC3331 has something to regulate against.

  • LTC3331 Battery charger enquiry

    Hello,

    As I was looking through the DC2151A EVM specs, I was wondering is it able to increase the battery charging further?

    Based on the data you have provided, if I lower R11 even further, is possible right? Or is there any limit to it?

  • About LTC3331 simulation in LTspice

    我通过LTspice模拟了LTC3331的工作状态,但发现在设置了相应的参数之后,芯片的VOUT引脚应为3.3V,但实际输出仅为329mv,我不知道问题出在哪里,谁可以给我一些指示

    I AM TRYING TO HARVEST ENERGY FROM PIEZO ELECTRIC MATERIALS, WHERE I CAME ACROSS LTC3331.

    I UNDERTAND THAT IT UTILISES THE BATTERY OR THE HARVESTED ENERGY ACCORDING TO THE AVAILABILITY. 

    IS AN EXTERNAL SUPPLY REQUIRED FOR POWERING THE IC ALONE.?

  • LTC3330 / LTC3331 minimum voltage

    Hi !

    I'm prototyping an energy harvester (solar and  vibration) for low voltage applications and I thought about the LTC3330 / LTC3331  ICs.

    My question is about the minum input voltage fro the ICs to work.

    1) First we have the diode bridges wiht a…
