Fluorescent Lamp DRVR 19-Pin DSO

The 2nd Generation Smart Ballast Control IC ICB2FL01G 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).

Integrated critical conduction mode PFC stage with excellent dynamic PFC performance enabling very low Low Total Harmonic Distortion (THD) across wide load ranges

Intelligent digital-/mixed-signal lamp inverter control

Integrated high-voltage level-shift half-bridge driver

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)
