High-voltage IC with PFC for advanced fluorescent linear ballasts.

International Rectifier introduced the IRS2168D fully integrated and protected high-voltage integrated circuit (HVIC) for advanced electronic linear fluorescent lamp ballasts which incorporate active power factor correction (PFC). The IC integrates PFC, ballast control and 600V half-bridge driver in a 16-lead SO package and features a wide range input voltage PFC to simplify complex multi-lamp circuits offering a fault counter on the current-sense pin for multi-lamp ballasts and cycle-by-cycle protection on the PFC side for high reliability. The IRS2168D's PFC circuitry provides a high power factor (PF) of 0.995, low total harmonic distortion (THD) of less than 10 percent and DC bus regulation within a tolerance of [+ or -]2.5 percent.
