5252F or YX805

 No, these are not secret callsigns from spy stations. These are small LED driver ICs. Ingenious small cheap devices that feature a solar charger and a step up converter. Probably every solar light has them inside.




Totally unaware of these devices I had a broken solar light that had a good battery and good LEDs. The switch was alright but it didn't switch on. To buy a new LED driver IC is just too expensive (€0,39 + €6,95 for postage). Luckily I had another solar light with a bad battery and salvaged parts to repair our broken light. It was a matter of exchange the IC and the coil. 

 More inside info can be found here:

If you click on the picture on the right you will have a larger one. The parts that I've exchanged are just near the second LED at the right.




We love solar lights in our garden!
