Step-down switching regulators, also called buck converters, output a regulated voltage level that is less than the input voltage. Modern step-down switching regulators and controllers are available with internal architectures that are optimized for applications that have specific goals, such as power savings, high efficiency, or low cost.
The most modern step-down regulators and controllers offer high switching frequencies, very efficient internal switching elements, and built-in circuit protections.
