They are switching regulators (also called switched mode power supplies (SMPS) or DC to DC converters) and have a typical efficiency between 80% to 95%. The available output current is a function of the input voltage, output voltage, and efficiency (see the Typical Efficiency and Output Current section below), but the input current can
