This document describes the high-power factor flyback converter for LED driver with the FL7732 PSR controller. It provides several features to enhance the performance of low-power flyback converters. By using single-stage topology with primary-side regulation, a LED lighting board can be implemented with few external components and minimized cost, without requiring an input bulk capacitor and feedback circuitry. Constant on-time control ensures precise constant-current control across changes in input voltage and output voltage. The operating frequency is proportionally changed by the output voltage to guarantee DCM operation with higher efficiency and simple design. FL7732 provides protection functions 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.
