Re: Solar panel charger with auto shutoff. Solar LED drivers.

It look like yx508 will only produce 1.2 volts to the led no matter what I change. The inductor was already a 47 uf. I tried changing it and when down to 10 uf and theRe was no increase in voltage. I'm looked at another solor light that put out 2.4 from a 1.2 battery and it had then 5252 chip, a 11 ...

Re: Solar panel charger with auto shutoff. Solar LED drivers.

Thanks for the response. My yx508 has 0128 below it. The voltage to the led is only 1.2 volts. If I put a 3.4 volts led it barely lights it. If I apply 3 volts to the same led directly it is much brighter. Does the chip itself suppose to increase then voltage or does the coil determine the final vol...

Re: Solar panel charger with auto shutoff. Solar LED drivers.

Hi, I'm new to the forum but I am impressed on the quality of responces. I was in the process of coverting a 99c solar light using a yx805 ic exactly like the one described here to use a 3.4 20ma color changing bulb. After trying to increase the voltage several different ways without changing the bo...
