LM2596 voltage regulator

When designing the entire control system, if the power supply system is too complex and redundant, it will not only cause electromagnetic interference to other circuits, but also have poor economic benefits. Therefore, all chips in the design are selected with 5 V, 3.3 V or 1.8 V power supply voltage. In this way, when designing the power supply, only three LM2596s and some capacitors, inductors, diodes, etc. are needed to directly convert the 24 V voltage into the required voltage. The circuit design is not only easy but also very economical. The power supply circuit is shown in Figure 6. When using it specifically, you can choose LM2596-5V, LM2596-3.3V, LM2596-1.8V chips as needed. To obtain +1.8 V and +5 V, use the connection method of Figure 6 (a), and to obtain +3.3 V, use the connection method of Figure 6 (b).
