I bought it for power-generating modules.
I am not an expert about these kind of things, so i bought it and follow the PDF file got from TI page.
I used rechargeable 3.6 V battery in J2 and put my power generator (thermoelectric generator, and its power output is several micro-watts and the voltage is over 130 mV) in J1.
If I set it correctly, I cloud turn the LED light on in J5. However, without battery, I cannot turn it on!
so, my question is..
1. Why should I use the battery? Is it necessary for using the whole circuit? or for lighting the LED?
2. Why I cannot turn the light on without battery?
3. Sadly, the LED turns on when I put the battery to J2. What did i wrong?
