The Smart Ballast IC is designed to control a Fluorescent Lamp Ballast including a Discontinuous Conduction Mode Power Factor Correction (PFC), a lamp Inverter Control and a High Voltage Level Shift Half-Bridge Driver.
The application requires a minimum of external components. There are integrated low pass filters and an internal compensation for the PFC voltage loop control. Preheating time is adjustable by a single resistor only in the range between 0 and 2000ms. In the same way the preheating frequency and run frequency are set by resistors only. The control concept covers requirements for T5 lamp ballasts such as detection of end-of-life and detection of capacitive mode operation and other protection measures even in multilamp topologies.
ICB1FL02G is easy to use and easy to design and therefore a basis for a cost effective solution for fluorescent lamp ballasts.
