DC-DC converter
a switching circuit that converts direct current (DC) of one voltage level to direct current (DC) of another voltage level. A typical DC-DC converter includes switches, a low pass filter (to attenuate the switching frequency ripple), and a load. The size of magnetic components and capacitors can be reduced and bandwidth can be increased when operating at high frequency. Most DC-DC converters are pulse-width modulated (PWM), while resonant or quasi-resonant types are found in some applications. Commonly used topologies include the buck converter, boost converter, buck-boost converter, and Cuk converter. Isolation can be achieved by insertion of a high frequency transformer.
