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

Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

Medical power supplies produce conditioned outputs for medical devices, instruments, and equipment

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

DC to AC inverters are used for converting direct current (DC) into alternating current (AC). They are also known as DC to AC converters

AC-DC adapters accept AC input voltage directly from a wall outlet, and output DC voltage

Power transformers convert power-level voltages from one level or phase configuration to another.  They can include features for electrical isolation, power distribution, and control and instrumentation applications

Valve positioners compare a control signal to a valve actuator’s position and move the actuator accordingly. They are used with both linear valves and rotary valves.

Thermoelectric coolers are solid-state heat pumps used in applications where temperature stabilization, temperature cycling, or cooling below ambient levels are required.

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

DC to AC converter chips transfer a DC input into AC power by using switching, inversion, or other technology

Power frequency converters take electrical input power at one frequency and voltage and provide electrical output power at a different frequency and at a different or equal voltage

AC to DC converter chips transfer an AC input into DC power using switching (MOSFET, IGBT) or rectification (diodes, Schottky diodes

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
