International Rectifier High-Voltage IC for Advanced Fluorescent Linear Ballasts

International Rectifier, IR a world leader in power management technology, today 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 new IC integrates PFC, ballast control and 600V half-bridge driver in a compact 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.

IR’s new ballast control IC utilizes IR’s advanced high-voltage IC process which incorporates next-generation high-voltage level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability.
