FL7732 - Fairchild Semiconductor

FL7732 Single-Stage PFC Primary-Side-Regulation Offline LED Driver

This highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters. The proprietary topology, TRUECURRENT® enables simplified circuit design for LED lighting applications. By using single-stage topology with primary-side regulation, a LED lighting board can be implemented with few external components an.
