Description
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 in serial multilamp topologies.
ICB1FL03G is easy to use and easy to design and
therefore a basis for a cost effective solution for
fluorescent lamp ballasts.
