International Rectifier Company introduces a new 600V fully integrated protective ballast control...
International Rectifier, a global leader in power semiconductors and management solutions, recently introduced a new 600V fully integrated ballast control IC. It features dynamic power factor correction for advanced linear fluorescent ballasts. Zeng Haibang, senior sales director for IR Asia Pacific, said: “Today, advanced linear fluorescent ballasts rely on PFCs to meet government regulations. Our new IRS2166D ballast control ICs feature a highly integrated and fully protected design. The ability to meet the designer's many features in a small footprint not only simplifies the design but also provides a high degree of programmability.†The latest IRS2166D integrates PFC, ballast control and half-bridge drivers in a compact single In the chip IC. Its PFC circuit operates in critical conduction mode with a power factor of 0.99, total harmonic distortion of less than 10%, and accurate DC bus regulation with a tolerance of 2.5%. There are many protection features in the device that can be programmed, including half-bridge overcurrent, dead time and warm-up time, warm-up and run frequency, and lamp life abort. Other features include fault protection when the lamp is not ignitable, filament fault protection, and DC bus undervoltage reset. The new devices are available in 16-pin DIP and SO lead-free packages with 50% duty cycle, integrated bootstrap circuitry, 15.6V Zener diode clamping voltage and 250μA typical micropower startup current. The latest ballast control ICs feature IR's advanced high voltage IC process, combined with next-generation high voltage level shifting and IC termination technology to provide superior electrical overstress protection and higher field reliability. The new devices are now available in volume order, and all products are in compliance with the Restriction of Hazardous Substances Directive (RoHS).
