mWSaver™ PWM Controller for Flyback Converter, 65KHz, X-Cap discharge

The FAN6757 is a next-generation Green Mode PWM controller with innovative mWSaver™ technology, which dramatically reduces standby and no-load power consumption, enabling conformance to worldwide Standby Mode efficiency guidelines. An innovative AX-CAP® method minimizes losses in the EMI filter stage by eliminating X-cap discharge resistors while meeting IEC61010-1 safety requirements. Protections ensure safe operation of the power system in various abnormal conditions. A proprietary frequency-hopping function decreases EMI emission. Built-in synchronized slope compensation allows more stable Peak-Current-Mode control over a wide range of input voltage and load conditions. The proprietary internal line compensation ensures constant output power limit over the entire universal line voltage range. Requiring a minimum number of external components, FAN6757 provides a basic platform that is well suited for cost-effective flyback converter designs that require extremely low standby power consumption.
