What is buck converter?
|
A buck converter is a step-down DC/DC converter, that is, its output DC voltage is lower than its input DC voltage. It refers to a class of switching-mode power supply (SMPS) that generally has two semiconductor switches (a diode and a transistor) and at least one energy storage element, such as a capacitor. As opposed to a voltage divider circuit, buck converters do not waste as much energy—they can be up to 95 per cent efficient for ICs—and are self-regulating (see voltage regulator). |
