  • Utsource Electronic Components Sg6961sz - China

    price: 0.48 Dollar US$

    1. Description
    The SG6961 is an 8-pin boundary mode PFC controller IC intended for controlling PFC pre-regulators. The SG6961
    provides a controlled on-time to regulate the output DC voltage and achieve natural power factor correction. The maximum on-time of the external switch is programmable to ensure safe operation during AC brownouts. An innovative multi-vector error amplifier is built in to provide rapid transient response and precise output voltage clamping. A built-in circuit disables the controller if the output feedback loop is opened. The start-up current is lower than 20μA and the operating current is under 4.5mA. The supply voltage can be up to 20V, maximizing application flexibility.
    2. Features >Boundary Mode PFC Controller
    >Low Input Current THD
    >Controlled On-Time PWM
    >Zero-Current Detection
    >Cycle-by-Cycle Current Limiting
    >Leading-Edge Blanking Instead of RC Filtering
    >Low Start-up Current (10μA Typical)
    >Low Operating Current (4.5mA Typical)
    >Feedback Open-Loop Protection
    >Programmable Maximum On-Time (MOT)
    >Output Over-Voltage Clamping Protection
    >Clamped Gate Output Voltage 16.5V
