Typical Latched shut-down upon mains overvoltage application for L6566B Multi-mode controller for SMPS Power Supplies

Typical Latched shut-down upon mains overvoltage application for L6566B Multi-mode controller for SMPS Power Supplies. The L6566B is an extremely versatile current-mode primary controller ICs, specifically designed for high-performance offline fly back converters. It is also suited for single-stage single-switch input-current-shaping converters (single-stage PFC) for applications supposed to comply with EN61000-3-2 or JEITA-MITI regulations
