    Flyback Controller, Voltage Control, 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 UC1825 family of PWM control ICs is optimized for high frequency switched mode power supply applications. Particular care was given to minimizing propagation delays through the comparators and logic circuitry while maximizing bandwidth and slew rate of the error amplifier. This controller is designed for use in either current-mode or voltage mode systems with the capability for input voltage feed-forward.

    Compatible with Voltage or Current Mode Topologies
    Practical Operation Switching Frequencies to 1MHz
    50ns Propagation Delay to Output
    High Current Dual Totem Pole Outputs (1.5A Peak)
    Wide Bandwidth Error Amplifier
    Fully Latched Logic with Double Pulse Suppression
    Pulse-by-Pulse Current Limiting
    Soft Start / Max. Duty Cycle Control
    Under-Voltage Lockout with Hysteresis
    Low Start Up Current (1.1mA)
