    產(chǎn)品信息

    The MC34025 series are high speed, fixed frequency, double-ended pulse width modulator controllers optimized for high frequency operation. They are specifically designed for Off-Line and DC-to-DC converter applications offering the designer a cost effective solution with minimal external components. These integrated circuits feature an oscillator, a temperature compensated reference, a wide bandwidth error amplifier, a high speed current sensing comparator, steering flip-flop, and dual high current totem pole outputs ideally suited for driving power MOSFETs.
    Also included are protective features consisting of input and reference undervoltage lockouts each with hysteresis, cycle-by-cycle current limiting, and a latch for single pulse metering.
    The flexibility of this series allows it to be easily configured for either current mode or voltage mode control.
    • 50 ns Propagation Delay to Outputs
    • Dual High Current Totem Pole Outputs
    • Wide Bandwidth Error Amplifier
    • Fully-Latched Logic with Double Pulse Suppression
    • Latching PWM for Cycle-By-Cycle Current Limiting
    • Soft-Start Control with Latched Overcurrent Reset
    • Input Undervoltage Lockout with Hysteresis
    • Low Start-Up Current (500
    • A Typ)
    • Internally Trimmed Reference with Undervoltage Lockout
    • 45% Maximum Duty Cycle (Externally Adjustable)
    • Precision Trimmed Oscillator
    • Voltage or Current Mode Operation to 1.0 MHz
    • Functionally Similar to the UC3825 Simplified
    • Pb-Free Packages are Available
