IR's 'Mini8' ballast control IC in 8-pin SO-8
International Rectifier, has introduced the IRS2526DS 'Mini8' compact fluorescent lamp (CFL) ballast control IC. Available in an 8-pin SO-8 package.
IR says 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 and 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 conditions such as mains interrupt or brownout, lamp non-strike, lamp filament failure and end-of-life. The new device incorporates an internal frequency either to reduce conducted EMI, ignition control to reduce inductor size, and end-of-life detection. The new IRS2526DS is targeted at applications that do not require PFC or utilize an external PFC controller.
"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," said Tom Ribarich, IR's director, Lighting Systems and Applications, Energy Saving Products Business Unit.
