Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

In Part 1 of this two-part series, “Creating Uniform LED Luminescence in RGB Displays”, the discussion focused on dot correction. This design technique is used for managing individual pixel brightness ...

A pair of dimmable, ac-dc digital pulse-width modulation (PWM) controllers for 100-V/230-V ac offline LED lighting applications illustrates the design complexity of what at first glance seems a simple ...

The GLCD 30 series of universal-input, constant-current 30-W LED drivers offers three-way dimming: 0 to 10 V dc, pulse-width modulation, and 10- to 100-kΩ resistance external dimming control. The GLCD ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of generating a ...

A UK manufacturer has invented the world's first commercially available led driver that can control the led current from one millionth of an Amp to over 2.1 Amps in a single output stage. According to ...

Remember when Apple introduced a parallax effect to iOS, giving the illusion that your icons are floating above the background? It was a cool albeit novel feature, but it also gave some users ...
