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 ...

Power Integrations, a provider of high-voltage integrated circuits for power conversion, announces the latest application of its innovative power conversion technology, unveiling a simple, ultra-low ...

[Peter] needed to drive a high power LED for his microscope. Rather than pick up a commercial LED driver, he built a simple constant current LED driver and fan control. We’ve featured [Peter’s] ...

SOME MULTI-STRING LED MODULES come with a common-anode configuration. The commonanode connection reduces the number of wires between the LED module and its driver from 2N to N+1, where N is the number ...

This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with many integrated analog features. The LED driver ...

Nearly all lighting applications today use LEDs. In a relatively short amount of time, they have become established as the preferred choice of illumination. However, in most applications, an LED can’t ...

In this article, we continue our discussion on the importance of grounding when installing LED lighting equipment. Part 1 of this three-part series focuses on the ground plane of the printed circuit ...

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 ...

[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 ...

Research in LED drivers and power converters continues to drive advances in efficient energy management and precision control for modern lighting applications. These systems are crucial to optimising ...
