While EMGs are based on Faraday's law of electromagnetic induction, suitable for large-scale power generation, PENGs can convert tiny physical deformations into electricity in self-powered, ...

This is a design idea of high efficiency constant current buck converter for LED lighting using LinkSwitch-TN. It operates in an input voltage ranging from 108 VAC to132 VAC and delivers an output of ...

The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...

Toshiba America Electronic Components, Inc. (TAEC)* today announced a new charge pump DC/DC converter IC that drives the white light-emitting diodes (LEDs) used to backlight liquid-crystal display ...

Current sources provide reliable current levels for electrical component testing and for powering specialized components such as lasers. Current (or power) levels will remain constant during variation ...

An IC with a buck regulator, boost regulator, and a linear charger combine to seamlessly maintain a constant VOUT even if VIN drops out for a short time. The IC can aid solid state drives that ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...
