    Products Detail

    The STCH03 is a current-mode controller designed for offline quasi-resonant ZVS flyback converters. It integrates a high-performance low-voltage PWM controller and a 650V HV start-up cell in an SO8 package. Key features include constant current output regulation using primary-sensing feedback, quasi-resonant operation with zero-voltage-switching, intelligent frequency jitter for EMI suppression, and ultra-low standby power consumption (under 10 mW at 230 VAC). It also provides comprehensive protection functions such as overvoltage protection (OVP), undervoltage protection (UVP), and thermal shutdown.

    Key Features

    • Input voltage feedforward compensation
    • Embedded thermal shutdown
    • Intelligent frequency jitter for EMI suppression
    • SO8 package
    • 650 V embedded HV start-up circuit with zero power consumption
    • Quasi-resonant (QR) zero-voltage-switching (ZVS) operation
    • Accurate and adjustable output OVP with auto-restart or latched options
    • Output undervoltage protection (UVP) with auto-restart
    • Fully integrated primary side constant current output regulation (CC)
    • Ultra-low standby power consumption (under 10 mW at 230 VAC)

    Application scenarios

    • AC-DC chargers for smartphones
    • tablets
    • camcorders and other handheld equipment; AC/DC adapters for STB
    • notebooks and auxiliary power supplies; USB power delivery fast charger
