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 a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

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 ...

The rear light is of utmost importance for road safety. However, since the space required on the electrical module is limited, several functions must be implemented using just one circuit, for example ...

That means the LED is operating at maximum efficiency no matter what dimming level is used. PWM, which is simple to implement and control with inexpensive digital circuitry, also offers an efficiency ...

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 ...

Linear Technology Corp. introduces the LT3761, a dc/dc controller designed to operate as a constant-current source and constant-voltage regulator. It also features a programmable internal PWM dimming ...

Electronics enthusiasts looking for a way to add a retro LED matrix to their project may be interested in a new piece of hardware which is now available from the Adafruit online store, in the form of ...

Sunpower’s DAP-04 DALI to PWM converter is designed to provide DALI control in LED lighting applications. The DAP-04 has a DALI input that can accept data from a remote IEC62386-101, 102 or 207 ...
