KKA3354 Description
The bipolar monolithic integrated circuit triggers, monitors and turns-off RF-oscillation of an electronic ballast for fluorescent lamps dependent on several controland monitoring functions.
KKA3354 Key Features
- 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 trigg
- The IC has a timer with low-active output which is activated for one second after supply voltage was applied. The switch
- The IC consists an error indication input. In case of error indication the IC stops oscillation. Enquiry cycles realize
- After lamp change the IC starts oscillation again
- The IC protects from overtemperature cutting oscillation. It is programmable when the oscillator circuit shall be trigge
