描述 Description

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).

特性 Features

? 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)

優(yōu)勢:
? 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
