●Description:
●The 2nd Generation Smart Ballast Control IC ICB2FL02G integrates all functions required to operate FL lamps such as preheat-, ignition- and run-mode and protection features. Digital mixed-signal power control is employed enabling speedy, cost-effective and stable ballast designs with a minimum number of external components. Reliable and robust high voltage isolation is achieved using Infineon’s proprietary Coreless Transformer Technology (CLT). The ICB2FL02G is functionally similar to the ICB2FL01G with a number of optimizations to operating frequencies and detection thresholds for dimmable ballast designs.
●Summary of Features:
● Integrated critical conduction mode PFC stage with enhanced dynamic PFC performance over wide load range
● Intelligent digital-/mixed-signal lamp inverter control
● Integrated high-voltage level-shift half-bridge driver
● Optimized for dimmable FL/CFL ballasts
● Drives up to 4 lamps with few external components required
● Built-in protection functions such as Over-Voltage Protection (OVP) and Over-Current Protection (OCP)
● Adjustable end-of-life detection in multi-lamp topologies and detection of capacitive mode operation
● Able to handle lamp chokes with high saturation behavior
● Special in-circuit test mode for faster test time
● Parameters set with resistors only
● Separate adjustable levels of lamp overload and rectifier effect detection (EoL1, EoL2)
● Intelligent discrimination between surge and half-bridge overcurrent events
● Self-adapting dead time adjustment of the half-bridge driver
● Highly accurate timing and frequency control over wide temperature range (-25 to 125 °C)
●Benefits:
● Reduced BOM cost by optimized lamp choke size
● Halving the time for key tests such as end-of-life detection and preheat/operation modes
● Reduced system cost and improved ballast stability
● Suitable for dimming & multi-power ballasts
● Enables ballast compatibility with a wider range of lamp types
● Lamp can automatically restart following surge events and handle correctly EOL events
● Eases design of multi-power ballasts and reduces EMI
● Reliable, stable ballast designs
