DC-DC converter chips provide a regulated DC voltage output from a different, unregulated input voltage.

IC switching voltage regulators are integrated circuits (ICs) that store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance switch.

Power transformers convert power-level voltages from one level or phase configuration to another.

Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters.

Power supplies are devices that produce AC or DC power.

Scan and video converters transform a digital computer image to a standard video signal for use with broadcasting or video devices such as televisions, monitors, or VCRs or vice versa

Analog-to-digital converter (ADC) chips transform information from analog to digital form
