4. IR2520D Ballast Control IC
The IR2520D is intended for driving CFL and TL lamps in CFL or small size ballasts applications.
The IR2520D integrates all of the necessary functions for preheat, ignition and on-state operation of
the lamp, plus, lamp fault protection and low AC-line protection, together with a complete high- and
low-side 600V half-bridge driver, the IR2520D has only 8 pins and fits into a standard SO8 or DIP8
package. The IR2520D has been designed to overcome the disadvantage of discrete self-oscillat-
ing solutions while maintaining low cost.
In the CFL market, the self-oscillating bipolar transistor solution remains very popular. This ap-
proach is very simple in nature but has many disadvantages including: DIAC or additional circuit
required for starting, additional free-wheeling diodes required, operating frequencies determined
by bipolar transistor storage time and toroid saturation (not easy to design, very dependent on
tolerances in production and difficult to set the frequencies precisely), unreliable “always hot” PTC
thermistor used for preheat that often fails in the field, no protection against lamp non-strike or open
filaments conditions, no smooth frequency ramping during ignition, capacitive mode operations,
high crest factor in the lamp current. These drawbacks can result in high susceptibility to components
and load tolerances, short lamp life and/or catastrophic failure of ballast output stage components.
The heart of the IR2520D is a voltage controlled oscillator (VCO) with externally programmable mini-
mum frequency and 0-5VDC analog voltage input. The IC includes adaptive zero-voltage switching
