Fairchild FAN6300 Series Quasi-Resonant PWM Controller Application Note
The document describes the highly integrated FAN6300/A/H PWM controller, which enhances flyback converter performance. The FAN6300/A models are designed for Quasi-Resonant operation below 100kHz, while the FAN6300H is suitable for high-frequency operation around 190kHz. Key features include a built-in High Voltage startup circuit to reduce startup time and an internal valley voltage detector to ensure quasi-resonant operation across wide line voltages.
