In part one of this series, we thrashed out the basics of LED lighting sources and their driving requirements. The performance of simple driving techniques, such as voltage sources/ballast resistors ...

Rated at 600 V, the IRS2980 buck LED driver is the first in a family of high-voltage LEDrivIR ICs that uses hysteretic average current mode control for precise current regulation. This buck regulator ...

As high-brightness LEDs (HBLEDs) penetrate all avenues of the lighting market, various semiconductor manufacturers are offering constant-current drivers. Here's what you need to know before you set ...

Hysteretic current control and high-side current sensing makes the HV9918 buck-mode LED driver IC ideal for a variety of solid-state lighting applications, such as low voltage industrial and ...
