Simple 5V 1A Switching regulator by IC LM2575-5.0

The switching regulator which used LM2575-5.0 in this page. You can make the stable voltage by using the 3 terminal regulator like LM317. However, because the output electric current and the inputted electric current are the same approximately, the difference between the input electric power (The input voltage x The input electric current) and the output power (The output voltage x The output current) is consumed as the heat with the regulator. Because it is, the efficiency isn’t good.
