Smart Ballast Control 19-Pin DSO

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.

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)
