A switching regulator is a circuit that uses a power switch, an inductor, and a diode to transfer energy from input to output. The basic components of the switching circuit can be rearranged to form a step-down (buck)converter, a step-up (boost) converter, or an inverter (flyback). Feedback and control circuitry can be carefully nested around

Linear Power Supplies. A linear power supply is, in many ways, the classic choice. It operates by taking the input voltage, and then, through a combination of transformers, diodes, and filters, provides a steady, direct current (DC) output. The process, however, can lead to some energy loss in the form of heat.
