... Also available LEAD-FREE (PbF) Description The IR2520D( 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 voltage con- trolled oscillator with externally programmable minimum frequency ...

... IR2520D(S)& (PbF) Absolute Maximum Ratings Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param- eters 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. ...

... Functional Description Under-voltage Lock-Out Mode The under-voltage lock-out mode (UVLO) is defined as the state the IR2520D is in when VCC is below the turn-on threshold of the IC. The IR2520D UVLO is designed to main- tain an ultra-low supply current (I QCCUV guarantee that the IR2520D is fully functional before the high- and low-side output gate drivers are activated ...

... Fig. 4 Resonant tank Bode plot with lamp operating points. 8 Run Mode The IR2520D enters RUN mode when the voltage on pin VCO exceeds 4.8V (V the ballast output stage becomes a low-Q, series-L, paral- lel-RC circuit. Also, the VS sensing and fault logic blocks (Figure 5) both become enabled for protection against non- ZVS and over-current fault conditions ...

... This will cause capacitive switching (hard-switching) resulting in high peak MOSFET currents that can damage them. The IR2520D will increase the fre- quency in attempt to satisfy ZVS until the VCO pin de- creases below 0.82V (V Mode and latch the LO and HO gate driver outputs ‘low’ for turning the half-bridge off safely before any damage can occur to the MOSFETs ...

... LO is ‘high’ (after the 1us blank time) and the peak current exceeds the average by 5 (CSCF), the IR2520D will enter Fault Mode and both LO and HO outputs will be latched ‘low’. The half-bridge will be safely disabled before any damage can occur to the ballast components. ...
