摘要

The 600V IRS2980 buck-regulator-control IC targets applications in LED-light-bulb replacement; LED-tube lighting, and other nonisolated LED-driver applications. The device uses hysteretic average-current-mode control for precise current regulation. The LED buck 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 to 100% current control. The IRS2980 is available in an SO-8 package at prices starting at 60 cents (10,000).
