Due to their high light (lumen) output per watt, HID lights work well in large indoor and outdoor public areas. They are also being increasingly used for vehicle headlights, projection TVs and displays.

Features and Benefits

  • HID ballasts require sophisticated wattage control. The embedded EERPROM on the Atmel AT90PWM stores tube wattages and parameters for accurate wattage detection and parameter adjustment without additional components.
  • Integrated Power Stage Controllers (PSCs) reduce electrical magnetic interference (EFI), manage lamp power, and control voltage in HID lamps.
  • To accelerate time to market, the Atmel ATAVRFBKIT light ballast demonstration kit incorporates a broad range of design features, including universal line input, low harmonic distortion, low stand-by power and aging protection features.

HID Ballasts

  • Digital HID ballasts are fast replacing magnetic HID ballasts because of their significant energy and cost savings.

With the Atmel AT90PWM microprocessor family, you can embed up to three Power Stage Controllers (PSCs) to drive your lighting system according your lamp power.
