    Flyback Controller, Current Control, UC18/UC28/UC38 Series, Texas Instruments


    The isolated-flyback power supply controller provides Constant-Voltage (CV) and Constant-Current (CC) output regulation to improve transient response to large load steps. Primary-Side Regulation (PSR) eliminates the need for an Optocoupler.

    The Texas Instruments UC3843A family of control devices is a pin-for-pin compatible improved version of theUCx84x family. Providing the necessary features to control current-mode or switched-mode power supplies, this family of devices has many improved features: start-up current is less than 0.5 mA, oscillator discharge is trimmed to 8.3 mA, and during UVLO, the output stage can sink at least 10mA at less than 1.2 V for VCC over 5 V.

    Optimized for Off-Line and DC-DC Converters
    Low Start-Up Current (< 0.5 mA)
    Trimmed Oscillator Discharge Current
    Automatic Feedforward Compensation
    Pulse-by-Pulse Current Limiting
    Enhanced Load Response Characteristics
    Under voltage Lockout With Hysteresis
    Double Pulse Suppression
    High-Current Totem Pole Output
    Internally-Trimmed Bandgap Reference
    Up to 500-kHz Operation
