IR Announces Cost Effective, Non-isolated, High Performance, High-Voltage IRS2980 LEDrivIR™ IC

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.

“In the rapidly growing solid state lighting sector, there is a need for low cost driver electronics to supply constant current output to high brightness, high power LEDs. The new IRS2980 LEDrivIR™ IC offers improved performance at a lower system cost than alternative solutions for non-isolated LED driver applications,” said Peter Green, LED Group Manager, IR’s Energy Saving Products Business Unit.

Available in an SO-8 package, the IRS2980 utilizes IR’s advanced high-voltage IC process which incorporates latest-generation high-voltage level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability, in addition to other new features and enhancements.
