Figure 1 Typical Application Circuit of Ballast for a Single Fluorescent Lamp
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 to
design 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.
