Description

This is ADAPTIVE BALLAST CONTROL IC. Data Sheet No. PD60212 revC IR2520D(S) & (PbF) ADAPTIVE BALLAST CONTROL IC 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) Packages 8-Lead PDIP IR2520D 8 Lead SOIC IR2520DS Description The IR2520D(S) 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 p.
