CCFL inverter delivers sure strikes

Sunnyvale, Calif. – Maxim Integrated Products’ MAX8729 is a fully integrated controller optimized to
drive multiple cold-cathode fluorescent lamps (CCFL) used in LCD monitor and TV applications. Using a topology that the company touts as unique, the controller works in a resonant mode during striking and switches over to a fixed-frequency mode after the lamps are lit to ensure reliable striking and operation under all conditions while reducing electrical stress on the transformer.
