International Rectifier IRS2980 high-voltage buck regulator control IC

International Rectifier has available 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 regulator is the first in a family of high-voltage LEDrivIR ICs, and uses hysteretic average current mode control for precise current regulation. The driver features low-side MOSFET drive with a high-voltage internal regulator and high-side current sensing.

The converter is compatible with electronic PWM dimming allowing for 0-100% current control.

Available in an SO-8 package, the device uses the company’s high-voltage IC process which incorporates latest generation high-voltage level-shifting and termination to deliver electrical over-stress protection and higher field reliability.
