Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
Most electronic equipment requires a DC power source in the range of 5-15V. Therefore, there are three types of dual power supply. 5 Volt Dual power supply circuit; 12 Volt Dual power supply circuit; 15 Volt Dual power supply circuit; All these circuits have individual step-down transformers and voltage regulators.
power consumption from the battery in low power applications. The TPS22916 load switch features an RON of 70 mΩat 3.6 V input voltage. When powering a 55 mA load, this switch reduces the output voltage by only 0.1%. This amount of drop has an insignificant impact on battery life. Figure 3. Inrush Current Control

The highest performance (most power efficient/coolest) method is to use a FET OR-ing setup. Their primary advantage is a near-zero voltage drop, limited only by the R DS(on) of the FET and current sense resistor (10 mΩ total resistance is fairly easy, but 1-2 mΩ if you really need).. Controllers for said systems typically use a low-value sense resistor and appropriately-sized …
