The IRS2980 LEDrivIR is a 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 uses hysteretic average current mode control for precise current regulation. The device is available in an SO-8 package, and is lead free and RoHS compliant.
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. Using the company’s high-voltage IC process that incorporates high-voltage level-shifting and termination technology, the device is claimed to deliver sound electrical over-stress protection and higher field reliability, in addition to other features and enhancements.
