CFL ballast controller

11 July 2012 Opto-Electronics

The IRS2526DS from International Rectifier is a ‘Mini8’ 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 IC features a 600 V half-bridge control circuit working at 50% 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 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 utilises the proven technology also featured in the previously released IRS2580DS ‘Combo8’ that combines a full featured fluorescent ballast with power factor correction (PFC) controller in a compact 8-pin package. The IRS2526DS is targeted at applications that do not require PFC or utilise an external PFC controller.
