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.

FEATUREs
■ Single-Ended Topologies, such as Flyback and Forward Converters
■ mWSaver™ Technology
   - Achieves Low No-Load Power Consumption:
      < 30 mW at 230 VAC (EMI Filter Loss Included)
   - Eliminates X Capacitor Discharge Resistor Loss with AX-CAP® Technology
   - Linearly Decreases Switching Frequency to 23 kHz
   - Burst Mode Operation at Light-Load Condition
   - Impedance Modulation in “Deep” Burst Mode
   - Low Operating Current (450 µA) in Deep Burst Mode
   - 500 V High-Voltage JFET Startup Circuit to Eliminate Startup Resistor Loss
■ Highly Integrated with Rich Features
   - Proprietary Frequency Hopping to Reduce EMI
   - High-Voltage Sampling to Detect Input Voltage
   - Peak-Current-Mode Control with Slope Compensation
   - Cycle-by-Cycle Current Limiting with Line Compensation
