FL7730MY - Fairchild Semiconductor

FL7730MY Single-Stage Primary-Side-Regulation PWM Controller

This highly integrated PWM controller, FL7730MY, provides several features to enhance the performance of single-stage flyback converters. The proprietary topology, TRUECURRENT™, enables the simplified circuit design for LED lighting applications. TRIAC dimming is smoothly managed by dimming brightness control without flicker. By using single-stage topology w.
