Hello,
I'm using LM2596 for the power supply of SIM800 GSM module.
LM2596 is stepping down voltage to 3.8V. I have attached schematic diagram of it.
It is working good if I use 12V-5A SMPS as power source. But when I use other supply like 24V-2A, LM2596 burns out while SIM800 is registering on network(during this time SIM800 draws more current). I'm not getting why it is burning out.
