IRS2526DS ‘Mini8’ Ballast Control IC

1. IRS2526DS ‘Mini8’ Ballast Control IC PRESS RELEASE DATA SHEET The IRS2526DS ‘Mini8’ is a 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. HI-RES GRAPHIC Lighting HOME PAGE • Advantages • The IRS2526DS features a 600V 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 included for protection against such conditions as mains interrupt or brown-out, lamp non-strike, lamp filament failure and end-of-life. • The device incorporates an internal frequency dither to reduce conducted EMI, ignition control to reduce inductor size, and end-of-life protection. • 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. • Features • 600V half-bridge control circuit • Single analog-to-frequency input pin • Fault protection circuitry • Internal frequency dither to reduce conducted EMI • Ignition control • End-of-life detection November 2011
