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 ...

Driver electronics within most LED bulbs incorporate Buck, Buck-Boost or Flyback converters. In each case the basic circuit can be modified to make it dimmable with acceptable performance met without ...

LEDs are more efficient than incandescent lights and can last 100 times longer, but they require specialized electronic-drive circuits to avoid overstress ...

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...

Power Integrations announced four reference designs describing drivers for dimmable PAR 30 and PAR 38 LED light bulbs. Jointly developed by Power Integrations and CREE, the designs showcase the ...

Electromagnetic emissions from an LED driver thus can be transferred via the power-supply lines as well as magnetically or capacitively coupled into adjacent circuit segments.

Protect your LED lighting circuits Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent ...

[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… ...

In common with all Power Integrations products, LYTSwitch-1 LED driver ICs have a host of protection features including thermal foldback with end-stop shutdown, short circuit protection, input and ...

While a non-dimmable LED may perform well in a circuit with a dimmer switch (incandescent or LED) set to 100 percent, there is a chance the light will flicker and hum at other brightness levels.
