Highly integrated quasi-resonant fly back controller suitable for designing high performance off-line power converters. It is suitable for AC-DC adapters and audio power applications. Notebook adapters and smart speakers & subwoofers end products.

• Integrated high−voltage start-up circuit with brownout detection
• Abnormal overcurrent fault protection for winding short circuit or saturation detection
• Internal temperature shutdown
• Valley switching operation with valley lockout for noise free operation
• Rapid frequency foldback for fast reduction of switching frequency at light loads
• Skip mode with quiet−skip technology for highest performance during light loads
• Frequency jittering for reduced EMI signature
• Latching or auto−recovery timer−based overload protection
• Adjustable Overpower Protection (OPP) and adjustable maximum frequency clamp
• CCM Operation During Power Excursion Mode (PEM)
