IR’s High-voltage IRS2980 LEDrivIR™ IC for Non-isolated LED Driver

IR’s High-voltage IRS2980 LEDrivIR™ IC for Non-isolated LED Driver Applications Offers Improved Performance and Greater Cost Efficiency

 

International Rectifier has introduced the IRS2980 high-voltage buck regulator control IC for LED light bulb replacement, LED tube lighting and other non-isolated LED driver applications.

 

Rated at 600 V, the IRS2980 is the first in a family of high-voltage LEDrivIR™ ICs, and utilizes hysteretic average current mode control for precise current regulation. The LED buck driver features low-side MOSFET drive with high-voltage internal regulator and high-side current sensing. The converter is compatible with electronic PWM dimming allowing for 0%-100% current control.
