Switching Regulator 电源入门资料DC-DC Converter Tutorial
Switching regulators offer higher efficiency than linear regulators. In addition,they can step-up, step-down and invert the input voltage. This article outlines the different types of switching regulators used in DC-DC conversion. It also reviews and compares the various control techniques for these converters.

What Is a Switching Regulator?
A switching regulator is a circuit that uses an inductor, a transformer, or a capacitor as an energy-storage element to transfer energy from input to output in discrete packets. Feedback circuitry regulates the energy transfer to maintain a constant voltage within the load limits of the circuit. The basic circuit can be configured to step up (boost), step down (buck), or invert output voltage with respect to input voltage.
