This is a design idea of high efficiency constant current buck converter for LED lighting using LinkSwitch-TN. It operates in an input voltage ranging from 108 VAC to132 VAC and delivers an output of ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

Most LED driver circuits use a series resistor to control the current through the LED. For applications needing a few LEDs, this is optimal. However, for applications needing many LEDs, this becomes ...

The HV9961, an average-mode, constant-control LED driver IC designed to drive LEDs using a buck topology, is well-suited for a variety of solid-state lighting applications. The HV9961 provides current ...

Infineon has brought out a constant current linear LED driver IC which provides low-voltage drop performance for regulating LED current. It is the second device released in the new generation BCR ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

Diodes has released simple LED driving chips for regulating current in strings of LEDs, particularly in cars and other road vehicles – some of which match parts from Infineon and Nexperia (see table ...

Consumer-based LED applications have really taken off. You now find them in home lighting, airplane cabin lights, automobile lights, MP3 players, and elsewhere. In the past, most LED drivers were ...
