IR2520DPBF Datasheet

Power Driver ICs


The IR2520DPBF is a complete adaptive ballast controller and 600V half-bridge driver integrated into a single IC for fluorescent lighting applications. The IC includes adaptive zero-voltage switching (ZVS), internal crest factor over-current protection, as well as an integrated bootstrap FET. The heart of this IC is a voltage controlled oscillator with externally programmable minimum frequency. All of the necessary ballast features are integrated in a small 8-pin DIP or SOIC package. IR2520DPBF Features • 600V Half Bridge Driver• Integrated Bootstrap FET• Adaptive zero-voltage switching (ZVS)• Internal Crest Factor Over-Current Protection• 0 to 6VDC Voltage Controlled Oscillator• Programmable minimum frequency• Micropower Startup Current (80uA)• Internal 15.6V zener clamp on Vcc• Small DIP8/SO8 Package• Also available LEAD-FREE (PbF)
