This is the circuit diagram of bipolar LED Driver using microcontroller. Here we use an LED which has a forward voltage drop of 2.2V and hence can be biased using a 5V supply. This Bipolar LED Driver ...

International Rectifier’s IRS29831 LEDrivIR integrates an LED driver controller and a 700-V MOSFET optimized for single-stage flyback and buck-boost topologies used in LED drivers, including LED bulb ...

An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. An LED-driver reference design for an LED replacement ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

A miniaturized driver manages red, green, blue, and white LEDs for maximum impact with minimal system CPU burden.

[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 great example ...

CCFL backlights are the most common backlight technology and are used in displays ranging from 5.7 to 23 in. or more diagonal. They can have from one to 24 or more lamps mounted along the edge of the ...

Schaffner has added the ED100/ED101 EMC filter series for LED driver circuits. The new filter’s common-mode inductance is matched by a substantial differential-mode inductance. With only one component ...
