FLS3247N - Fairchild Function Overview

The FLS3247N is a 1-stage PFC primary-side-regulation offline LED Driver with integrated power MOSFET. This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. The proprietary topology enables simplified circuit design for LED lighting applications. By using the 1-stage topology with primary-side regulation, an LED lighting board can be implemented with the few external components, requiring no input bulk capacitor or feedback circuitry. To implement good power factor and low THD, constant on-time control is utilized with an external capacitor connected to COMI. Precise constant-current control regulates accurate output current versus changes in input voltage and output voltage. FLS3247 provides protection features such as open-LED, short-LED and over-temperature protection. The current-limit level is automatically reduced to minimize the output current and protect external components in short-LED condition.
