This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

[michimartini] over on Hackaday.io loves playing with multivibrator circuits, and has come across a simple example of a ring oscillator. This is a discrete transistor RC-delay design utilizing five ...

In designs using multiple LED strings such as brake lights, daytime running lights, rear lights and other automotive lighting applications, current-balancing circuits supply equal current to all LED ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

A technical paper titled “Tunnel Junction-Enabled Monolithically Integrated GaN Micro-Light Emitting Transistor” was published by researchers at the Ohio State University and Sandia National ...

The single cell led flashlight circuit is a self-oscillating boost converter. A typical white LED has its best power-efficiency combination at about 20mA, and needs about 3.3V. This makes for a power ...
