This design example report is a 7 W TRIAC dimmable, high efficiency, power factor corrected, non-isolated buck LED driver employing LYTSwitch™-3 LYT3315D. It operates in an input voltage ranging from ...

This design example report describes a 20 W high efficiency TRIAC dimmable, power factor corrected LED driver employing LYTSwitch™-4 LYT4314E. This design operates an input voltage ranging from 190 ...

LED driver designs can deliver flicker-free and fast startup dimming performance while still providing high power factor and efficiency, writes Rich Miron Dimming performance of LED lamps in legacy ...

Tridonic is aiming at high-ceiling industrial led lighting with a 220W harsh environment constant-current driver. ‘LCI 220/500-1400/300 pD NF h28 PRE4’ (trips off the tongue… Ed) works across -40 to ...

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 ...

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 ...

[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] ...
