International Rectifier announces 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 employs 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% to 100% current control.

Available in an SO-8 package, the IRS2980 features the company's advanced high-voltage IC process, which incorporates high-voltage level-shifting and termination technology to offer superior electrical over-stress protection and higher field reliability.
