ADVANCE DATA Data Sheet No. PD60212 Rev A IR2520D(S) ADAPTIVE BALLAST CONTROL IC • • • • • • • • • Features 600V Half Bridge Driver Integrated Bootstrap Diode Adaptive zero-voltage switching (ZVS) Internal Crest Factor Over-Current Protection 0 to 5VDC Voltage Controlled Oscillator Programmable minimum frequency Micropower Startup Current (150uA) Internal 15.6V zener clamp on Vcc Small DIP8/SO8 Package 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 diode. 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.

All voltage parameters are absolute voltages referenced to COM, all currents are defined positive into any lead. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.

Please note that this pin should not be driven by a DC, low impedance power source greater than 6V. Note 2: This IC contains a zener clamp structure between the chip VCC and COM, which has a nominal breakdown voltage of 15.6V. Please note that this supply pin should not be driven by a DC, low impedance power source greater than the VCLAMP specified in the Electrical Characteristics section. Recommended Operating Conditions For proper operation the device should be used within the recommended conditions.
