IRS2526DS ‘Mini8’ CFL
International Rectifier has introduced the IRS2526DS ‘Mini8’ compact fluorescent lamp (CFL) ballast control IC, which is fully programmable and claimed to offer a high degree of accuracy and control for all lamp types.
Available in an eight-pin SO-8 package, the IC is designed to reduce component count, simplify circuit design and increase efficiency.
Featuring a 600V half-bridge control circuit working at 50 per cent duty cycle, the IRS2526DS also has variable frequency for driving the resonant-mode lamp output circuit.
The oscillator is controlled by a single analogue-to-frequency input pin used to set the different operating frequencies of the ballast.
