Part 2: A 60V buck-boost controller drives high power LEDs, charges batteries and regulates voltage with up to 98.5% efficiency at 100W and higher. Part 3: Offline LED lighting simplified: A high ...

When driving high-brightness LEDs with switching regulators, LED requirements will influence many details of regulator design including the methods used for closing the feedback loop and for LED ...

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most devices ...

Consumer demand and government initiatives to phase out inefficient lighting technologies are pushing expansion of LED lighting. Designers of these devices must satisfy not only end users, but also ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

Even in today’s digital, IT-intensive radio plant, there is still a need to design and build one-of-a-kind electronic circuits. Simple devices such as digital tone generators and small distribution ...

Time will always be“of the essence” for professional engineers and amateur enthusiasts alike. This can certainly be said about the process of designing circuits involving Light Emitting Diodes (LEDs).

All circuits, analog or digital, have characteristics dependent on the values of their component parts. Invariably, these parts are non-ideal in many ways. Even their most fundamental characteristics, ...
