Dear all,
I am using a LM2576 (5 Volt) switching regulator IC in my board, earlier it was working well for some time. When i switched on relays either small resistor type inductor is blowing or LM2576 is blowing up. To resolve it i have replaced diode 1N5822, 100uh inductor, LM2576, but still one of the two are blowing up. I have wasted couple of inductors and LM2576. My relay is connected to 24 volt power supply so no supply is going from the LM2576 regulator to the relay. I have tested capacitor also and it is in good condition.
I cant find where is the exact problem. What is the main reason for blow up of inductor or lm2576.
