FAN6756

FAN6756— mWSaver™ PWM Controller January 2013 FAN6756— mWSaver™ PWM Controller Features   Single-Ended Topologies, such as Flyback and Forward Converters mWSaver™ Technology Description The FAN6756 is a next-generation Green Mode PWM controller with innovative mWSaver™ technology, which dramatically reduces standby and no-load power consumption, enabling compliance with worldwide Standby Mode efficiency guidelines. An innovative AX-CAP® method minimizes losses in the EMI filter stage by eliminating the X-cap discharge resistors while meeting IEC61010-1 safety requirements. “Deep” Burst Mode clamps feedback voltage and modulates feedback impedance with an impedance modulator during Burst Mode operation, which forces the system to operate in a Deep Burst Mode with minimum switching losses. Protections ensure safe operation of the power system in various abnormal conditions. A proprietary frequencyhopping function decreases EMI emission and 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, FAN6756 provides a basic platform that is well suited for cost-effective flyback converter designs that require extremely low standby power consumption. - Achieves Low No-Load Power Consumption: < 30 mW at 230 VAC (EMI Filte...
