Hi, I have been using lm2596 recently for my project and encountered weird issue with it. I am using it to step down the voltage from my bike dynamo which is 16v down to 5V for my front and back tail lights. But it is getting burned I guess when I ride the bike and I had 3 times changed the lm2596 IC. Therefore, I dont know what is wrong with it. when it crashed, there was short circuit between in and out pin. Here is my schematics. Please let me know your opinions and give advice.
