    UCC3818ADR Description

    The UCC3818ADR is a high-voltage, high-power step-down switching regulator controller produced by Texas Instruments. It is specifically designed for off-line applications, such as power supply units (PSUs) for televisions, monitors, and other consumer electronics.

    Description:

    The UCC3818ADR is a monolithic integrated circuit that provides a complete solution for off-line power supply applications. It includes a high-voltage startup circuit, an under-voltage lockout (UVLO), a power save mode, and a thermal shutdown protection. The device also features a high-voltage power MOSFET driver and a current sensing circuit.

    Features:

    1. Wide input voltage range: The UCC3818ADR can operate with input voltages ranging from 45V to 65V, making it suitable for a variety of off-line applications.
    2. High output current: The device can deliver up to 3A of continuous output current, making it suitable for high-power applications.
    3. High efficiency: The UCC3818ADR features a high-efficiency synchronous rectification mode, which reduces power dissipation and improves overall efficiency.
    4. Power save mode: The device can enter a low-power mode during light load conditions, further improving efficiency and reducing power consumption.
    5. Thermal shutdown protection: The UCC3818ADR includes a thermal shutdown feature that protects the device from overheating.
    6. Under-voltage lockout (UVLO): The device has an integrated UVLO circuit that prevents it from operating if the input voltage falls below a certain threshold.
    7. High-voltage startup: The UCC3818ADR features a high-voltage startup circuit that allows it to operate with input voltages as low as 45V.

    Applications:

    1. Power supply units (PSUs) for televisions and monitors
    2. High-power consumer electronics
    3. Industrial power supplies
    4. Medical equipment power supplies
    5. Telecommunication equipment power supplies
    6. Computer power supplies

    In summary, the UCC3818ADR is a versatile and efficient step-down switching regulator controller designed for high-voltage, high-power off-line applications. Its wide input voltage range, high output current capability, and various protection features make it suitable for a wide range of power supply applications.
