Circuit Protection Requirements All LED drivers need various devices in multiple locations (Fig.2) to protect the circuitry from overvoltage and overcurrent events. Today, there are a few key industry ...

LED lighting is fast becoming the lighting design of choice for contemporary lighting projects, both residential and commercial. Touted for its green properties, such as low maintenance costs, long ...

The Fig. 1 example includes LED loads D1 + D2, D3 + D4, D5 + D6 and a power-supply output voltage, with a constant output current, providing the circuit input voltage (V IN).

Most small-size color LCD displays today use white LEDs for backlighting. These systems usually involve handheld devices with an LED drive circuit powered by a battery whose output ...

Circuit board design startup Quilter announced on Tuesday it raised $10 million, saying it would use artificial intelligence to reduce the time to design components that power electronics in ...

The question few of us ever ask is, how do they work? Most specifically—how do you design a circuit that’s intended to measure another circuit?

[Petteri Aimonen] created an omnidirectional LED safety light to cling to his child’s winter hat in an effort to increase visibility during the dark winter months, but the design is also grea… ...

The control circuit responds by increasing the PWM on-time to boost the output voltage higher in a failed attempt to increase the LED current. In most instances, the output voltage rapidly rises in an ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

To configure parallel drivers with high-side pass elements, however, the current-sense feedback circuitry must also be on the high side, and it must be able to withstand at least the voltage the ...

There you have it – an LED resistor value calculator can help streamline your LED circuit design projects and free up your time, in more ways than you might initially imagine.

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. Dubbed DER-322, the circuit is desigend to fit neat ...
