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 frequency- hopping 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. Applications Flyback power supplies that demand extremely low standby power consumption, such as: Adapters for Notebooks, Printers, Game Consoles, etc. Open-Frame SMPS for LCD TV, LCD Monitors, Printer Power, etc. Related Resources Evaluation Board: FEBFAN6756MR_T03U065A Ordering Information Part Number Protections (1) Operating Temperature Range Package Packing Method OLP OVP OTP SSCP FAN6756MRMY A/R L L A/R -40 to +105°C 8-Pin, Small Outline Package (SOP) Tape & Reel FAN6756MLMY L L L A/R Note: 1.
