    LT1766/LT1766-5
    5.5V to 60V 1.5A, 200kHz
    Step-Down Switching Regulator
    FEATURES DESCRIPTION n The LT®1766/LT1766-5 are 200kHz monolithic buck switching regulators that accept input voltages up to 60V. A high
    efficiency 1.5A, 0.2Ω switch is included on the die along
    with all the necessary oscillator, control and logic circuitry.
    A current mode control architecture delivers fast transient
    response and excellent loop stability. n Wide Input Range: 5.5V to 60V
    1.5A Peak Switch Current
    Constant 200kHz Switching Frequency
    Saturating Switch Design: 0.2Ω
    Peak Switch Current Rating Maintained Over
    Full Duty Cycle Range
    Low Effective Supply Current: 2.5mA
    Low Shutdown Current: 25μA
    1.2V Feedback Reference Voltage (LT1766)
    5V Fixed Output (LT1766-5)
    Easily Synchronizable
    Cycle-by-Cycle Current Limiting
    Small 16-Pin SSOP and Thermally Enhanced
    TSSOP Packages Special design techniques and a new high voltage process
    achieve high efficiency over a wide input range. Efficiency
    is maintained over a wide output current range by using the ...
