I have LM2576-5.0V fixed 5V output IC both SMD and Through hole. When I use through hole IC, circuit works fine. When i give 12V 2A adpter input, it gives me 5V 2A output and i can charge my 10400mAH powerbank. But when i use SMD IC, it can't give me output. All Components in circuit are same, only i change IC. What is my mistake? I prepared hardware as per datasheet. Here is IC images, which i use and schematic.
