2nd Generation FL Controller for Fluorescent Lamp Ballasts

Overview

TopologyOther Topology
Switching frequency20-120 kHz
IC revision1.1

Description

The FL controller ICB2FL03G is designed to control fluorescent lamp ballast, including a discontinuous mode Power Factor Correction (PFC), lamp inverter control and a high-voltage level shift half-bridge driver.The control concept covers requirements for T5 lamp ballasts for single and multi-lamp designs (series connection supported). ICB2FL03G is based on the 2nd-generation FL controller technology, is easy to use and simple todesign in. This makes the ICB2FL03G a basis for cost-effective solutions for fluorescent lamp ballasts with high reliability. Figure 1 shows a typical application circuit of ballast for a single fluorescent T8 lamp with current mode preheating.

Features

  • Discontinuous mode PFC for load range 0 to 100%
  • Integrated digital compensation of PFC control loop
  • Improved compensation for low THD of AC input current, also in DCM operation
  • Adjustable PFC current limitation

Typical applications

  • Bill of Material
  • Multi Lamp Ballast Topologies
  • Schematic Ballast 54W T5 Single Lamp
