STMicroelectronics | EVAL6574B

ST Microelectronics offers a complete tool line, tailored to the Evaluation Board for L6574 Electronic Ballast with PFC Using L6574 and L6561.

The L6574 is a high-performance ballast driver, designed using 600-V BCD offline technology, which ensures all the features needed to properly drive and control a fluorescent bulb. It is provided with built-in VCO start up sequence circuitry, protections, and operation amplifier for implementing a closed-loop control of the lamp current.

Features :

• High voltage rail up to 600 V
• dV/dt immunity ± 50 V/ns in full temperature range
• Driver current capability (250 mA source and 450 mA sink)
• Switching times 80/40 ns rise fall with 1 nF load
• CMOS shutdown input
• Under-voltage lock-out
• Preheat and frequency shifting timing
• Sense operational amplifier for closed-loop control or protection features
• High-accuracy current-controlled oscillator
• Integrated bootstrap diode
• Clamping on VS
• SO16, DIP16 package
