This is a project circuit in which we use PWM to dim the intensity of light of the LED. The Pulse Width Modulation (PWM) plays an important role in controlling the circuits. If you want to control the ...
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 ...

What is PWM dimming, and what are the alternatives?
Have you ever looked at your phone and gotten a headache? Sometimes, it just means you've been on it too long and need to take a break. For some folks like me, it's the display itself that's causing ...
How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...
The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...
Linear Technology has unveiled a new pulse width modulation (pwm) generator with 48 independent channels. According to the IC specialist, each channel has an individually adjustable 12bit (4,096 steps ...
You'll have to double check the compatibility of the PWM frequency with the LEDs in question (too high and they may not turn on), and also double check that it handles full 0% if you want to be able ...
Diodes has launched a boost/single-ended primary inductance converter (SEPIC) controller for various automotive LED applications. The AL8853AQ is an automotive-compliant and highly integrated ...
The concept: find a COTS* motorcycle LED light dimmer that can be spliced into an auxiliary LED light array to vary the light output. We found this “Rotary LED Dimmer”, made by ADVmonster and designed ...
