ICB2FL02G - LIGHTING MIXED SIGNA
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 Infineons 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 | Target Applications: FL/CFL Ballasts
