Fluorescent Lamp

Developed with Fairchild’s unique high-voltage process, Fairchild control ICs for fluorescent lamp application incorporates a preheating / ignition function to increase lamp life. The control IC detects an open-lamp condition, without the expense of external circuitry, and prevents stress on MOSFETs. The high-side driver built into the IC also incorporates a common-mode noise cancellation circuit that provides robust operation against high-dv/dt noise intrusion.

Design Advantages

  • Floating Channel Designed for Bootstrap Operation to +600V.
  • Adjustable Run Frequency and Preheat Time.
  • Internal Protection Function (Latch Mode).
  • Internal active Zero-Voltage Switching (ZVS) control circuit for open-lamp detection minimize the external circuitry, and prevents stress on MOSFETs.
  • Soft-Start Functionality.
