Description
The IR2520 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 diode. The heart of this IC is a voltage controlled oscillator with externally programmable minimum frequency.
