Abstract

The ATT2161/AT2162 integrated electronic ballast chip set includes control circuitry and integral high-voltage power FETs to operate fluorescent lamps. Programmable, dual-level current limit provides for filament preheating and overcurrent protection while self-resonant sense circuitry guarantees start-up. Steady state lamp power is governed by a precision oscillator. Dimming and high efficiency, low distortion power factor correction can also be accommodated
