The IRS2980 buck regulator is viable for LED light bulb replacement, LED tube lighting, and other non-isolated LED driver applications. Rated at 600 V, the devices employ hysteretic average current mode control for precise current regulation. Other features include low-side MOSFET drive via a high-voltage internal regulator and high-side current sensing and compatibility with PWM dimming allowing, for 0% to 100% current control. Available in an SO-8 package, pricing begins at $0.60 each/10,000. For more information, contact Sian Cummins at International Rectifier Corp., El Segundo, CA. (310) 252-7148.
