ICB1FL01G
Smart Ballast Control IC for
Fluorescent Lamp Ballasts
Product Highlights
⢠Lowest Count of external Components
⢠HV-Driver with coreless Transformer Technology
⢠Improved Reliability and minimized Spread due to
digital and optimized analog control functions
PG-DSO-18-1
Features PFC
Description
⢠Discontinuous Conduction Mode PFC
⢠Integrated Compensation of PFC Control Loop
⢠Adjustable PFC Current Limitation
⢠Adjustable PFC Bus Voltage
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.
Features Lamp Ballast Inverter
The application requires a minimum of external
⢠Supports Restart after Lamp Removal and End-of- components. There are integrated low pass filters and an
Life Detection in Multi-Lamp Topologies
internal compensation for the PFC voltage loop control.
⢠End-of-Life (EOL) detected by adjustable +/-
Preheating time is adjustable by a single resistor only in
Thresholds of sensed lamp voltage
the range between 0 and 2000ms. In the same way the
⢠Rectifier Effect detected by ratio of +/- Amplitude of preheating frequency and run frequency are set by
Lamp Voltage
resistors only. The control concept covers requirements
⢠Detection of different capacitive Mode Operations for T5 lamp ballasts such as detection of end-of-life and
⢠Adjustable Inverter Overcurrent Shutdown
detection of capacitive mode operation and other
⢠Self-adaption of Ignition Time from 40ms to 235ms protection measures even in multilamp topologies.
⢠Parameters adjustable by Resistors only
⢠Pb-free lead plating; RoHS compliant
ICB1FL01G is easy to use and easy to design and
therefore a basis for a cost effective solution for
fluorescent lamp ballasts.
