Characteristics of the IC
• The KKA3354 is a control- and monitoring-IC to drive an electronic ballast for fluorescent lamps.
• The IC actuates the oscillation of a self-oscillating circuit for generation of RF-shaped lamp current by
means of trigger pulses. After successful excitation the oscillation is monitored and further trigger pulses are
blocked.
• The IC has a timer with low-active output which is activated for one second after supply voltage was
applied.
The switching output is effective for pre-heating and ignition systems.
• The IC consists an error indication input. In case of error indication the IC stops oscillation. Enquiry cycles
realize interference reduction.
• After lamp change the IC starts oscillation again.
• The IC protects from overtemperature cutting oscillation. It is programmable when the oscillator circuit
shall be triggered again.
