Buck regulator IC offers improved performance at lower system cost
1 min read
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 600V, the device is the first in a new series of high voltage LEDrivIR ICs and utilises hysteretic average current mode control for precise current regulation.
The buck regulator features low side mosfet drive with high voltage internal regulator and high side current sensing. According to IR, it 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," said Peter Green, led group manager, IR's Energy Saving Products business unit. "The new IRS2980 LEDrivIR IC offers improved performance at a lower system cost than alternative solutions for non isolated led driver applications.
Available in an SO-8 package, the IRS2980 utilises IR's advanced high voltage IC process, which incorporates latest generation high voltage level shifting and termination technology. IR claims this delivers superior electrical over stress protection and higher field reliability.
