EL SEGUNDO, Calif.--([ BUSINESS WIRE ])--International Rectifier, IR (NYSE:IRF), a world leader in power management technology, today introduced the IRS2526DS aMini8a compact fluorescent lamp (CFL) ballast control IC that offers full programmability, and a high degree of accuracy and control for all lamp types. Available in an 8-pin SO-8 package, the new feature-rich IC reduces component count, simplifies circuit design and increases efficiency in a compact footprint.

"The IRS2526DS IC differs greatly from alternative approaches because it packs additional features and functionality not found in other solutions in an 8 pin package. It is very easy to use and enables customers to significantly speed up their design time to develop a highly efficient electronic ballast lighting solution"

The IRS2526DS features a 600 V half-bridge control circuit working at 50 percent duty-cycle and variable frequency for driving the resonant mode lamp output circuit. The high accuracy oscillator is controlled by a single analog-to-frequency input pin used to set the different operating frequencies of the ballast. Complete fault protection circuitry is also included for protection against such conditions as mains interrupt or brown-out, lamp non-strike, lamp filament failure and end-of-life. The new device also incorporates an internal frequency dither to reduce conducted EMI, ignition control to reduce inductor size, and end-of-life detection.

The IRS2526DS is the third generation ballast IC from IR and utilizes the proven technology also featured in the previously released IRS2580DS aCombo8a that combines a full featured fluorescent ballast with power factor correction (PFC) controller in a compact 8-pin package. The new IRS2526DS is targeted at applications that do not require PFC or utilize an external PFC controller.
