Switching regulators are introduced in these pages is the kind of down and is one to get the output voltage lower than input voltage. As for regulators who use this time, the output is a 5-V fixation. Switching regulator is made of a higher voltage than the input voltage. LM2575 series offers a high efficiency linear three popular replacement terminal regulators. This substantially reduces the size of the heat sink, and in many cases no heat sink is required. Standard series of inductors optimized for use with the LM2575 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. The following is a schematic drawing:

Other features include guaranteed ± 4% tolerance on output voltage within specified input voltages and output load conditions, and ± 10% in the oscillator frequency. External shutdown is included, featuring 50 μA (typical) standby current. Output switch includes cycle-by-cycle current limiting and thermal shutdown for full protection under fault conditions. The LM2575 regulator is a series of monolithic integrated circuits that provide all the active functions for step-down (buck) switching regulator, capable of driving a 1A load lines very well and load regulation. The tool is available in fixed output voltage 3.3V, 5V, 12V, 15V, and output versions can be arranged.
