    UC3846N Typical application Circuitry

    UC3846N

    The UC3846N is an integrated circuit (IC) designed as a current-mode pulse-width modulation (PWM) controller, widely used in power management applications such as switched-mode power supplies (SMPS) and DC-DC converters. Below are some of the key features and specifications of the UC3846N:

    1. Current-Mode Control: The UC3846N utilizes current-mode control, which provides several advantages including improved transient response, inherent loop stability, and simplified control loop design compared to voltage-mode controllers.

    2. Operating Frequency: The device can operate at a frequency of up to 500 kHz, which can be adjusted to suit different power supply applications.

    3. Under Voltage Lockout (UVLO): The UC3846N features under-voltage lockout to ensure that the IC becomes operational only when the supply voltage is within a specified range.

    4. Wide Input Voltage Range: The IC is designed to accommodate a wide range of input voltages, providing flexibility in power supply design.

    5. Output Overcurrent Protection: The UC3846N includes features for overcurrent protection to safeguard the power supply system from conditions of excessive current.

    6. Voltage Error Amplifier: The device integrates a voltage error amplifier to ensure that the output voltage accurately tracks the desired reference voltage.

    7. Oscillator with Synchronization Capability: The UC3846N includes an internal oscillator that can be synchronized with an external clock source for improved noise immunity and system coordination.

    8. Startup and Shutdown Features: The IC incorporates features such as soft-start and shutdown capabilities, ensuring smooth startup and safe shutdown of the power supply.

    9. Package: The "N" in the part number indicates that the device is typically available in a DIP (Dual Inline Package).

    10. Applications: The UC3846N is suitable for a variety of applications, including offline AC-DC converters, DC-DC converters, battery chargers, and other types of switched-mode power supplies.

    11. Trimmed Oscillator Discharge Current: The UC3846N may have a trimmed oscillator discharge current to ensure precise duty cycle control.

    12. Low Start-Up Current: The UC3846N is designed with a low start-up current, making it an efficient choice for battery-powered or energy-conscious applications.

    13. High Current Totem-Pole Output: The high current totem-pole output can efficiently drive the gate of a power MOSFET.

    14. Dual Push-Pull Outputs: The UC3846N includes dual push-pull outputs to provide complementary PWM outputs for driving push-pull converter topologies.

    For detailed information regarding electrical characteristics, pin configurations, and application guidelines, it is recommended to consult the datasheet for the UC3846N.
