Power supplies are devices that produce AC or DC power.

Frequency-to-current converters accept a frequency (an AC signal) and produce an output current whose value is a function of the input frequency

DC-DC converters accept DC input and provide regulated and/or isolated DC output in various applications including computer flash memory, telecommunications equipment, and process control systems

Voltage-to-frequency converter chips provide a signal frequency output as a function of an analog input voltage

Frequency-to-voltage converter chips provide an analog voltage output as a function of the input signal frequency

Digital parallel and serial converters change input streams of parallel data into output streams of serial bits, or vice versa

DC to AC inverters are used for converting direct current (DC) into alternating current (AC).
