Buck LED driver offers hysteretic current regulation

Buck LED driver offers hysteretic current regulation

Rated at 600 V, the IRS2980 buck LED driver is the first in a family of high-voltage LEDrivIR ICs that uses hysteretic average current mode control for precise current regulation. This buck regulator control IC targets LED light bulb replacement, LED tube, and other non-isolated LED driver applications.

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. Available in an SO-8 package, the IRS2980 features an offset voltage of 600 V, a frequency of 150 kHz max, an output source current of 180 mA minimum, and an output voltage of 9.0 V min and 16.6 V max.(From $0.60 ea/10,000; IRPLLED7 ref design, $99 — available now)
