A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

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 ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does ...

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 ...

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 ...

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 ...
