Hosted by Alix Paultre, the Tinker’s Toolbox is the Advantage Design Group’s web-based interview show where we talk about the latest technology, components, and design issues for the electronic design engineering community.
In this podcast we talk to Peter Green of International Rectifier about solid-state lighting and the circuits needed to drive them. The company is a leader in analog- and mixed-signal ICs, advanced circuit devices, integrated power systems, and components for the electronic design community. IR recently released the IRS2980 high-voltage buck regulator control IC for LED light bulb replacement, LED tube lighting and other non-isolated LED driver applications.

Here is the press release on the device:
International Rectifier, a world leader in power management technology, 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 600 V, the IRS2980 is the first in a family of high-voltage LEDrivIR ICs, and utilizes hysteretic average current mode control for precise current regulation. 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.
“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. The new IRS2980 LEDrivIR IC offers improved performance at a lower system cost than alternative solutions for non-isolated LED driver applications,” said Peter Green, LED Group Manager, IR’s Energy Saving Products Business Unit.
Available in an SO-8 package, the IRS2980 utilizes IR’s advanced high-voltage IC process which incorporates latest-generation high-voltage level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability, in addition to other new features and enhancements.
