    Monolithic 3A, 1.25MHz
    Step-Down Switching Regulator
    FEATURES DESCRIPTION n The LT®1765 is a 1.25MHz monolithic buck switching
    regulator. A high efficiency 3A, 0.09Ω switch is included
    on the die together with all the control circuitry required
    to construct a high frequency, current mode switching
    regulator. Current mode control provides fast transient
    response and excellent loop stability. 3A Switch in a Thermally Enhanced 16-Lead
    TSSOP or 8-Lead SO Package
    Constant 1.25MHz Switching Frequency
    Wide Operating Voltage Range: 3V to 25V
    High Efficiency 0.09Ω Switch
    1.2V Feedback Reference Voltage
    Uses Low Profile Surface Mount Components
    Low Shutdown Current: 15μA
    Synchronizable to 2MHz
    Current Mode Loop Control
    Constant Maximum Switch Current Rating at
    All Duty Cycles*
    Available in 8-Lead SO and 16-Lead Thermally
    Enhanced TSSOP Packages New design techniques achieve high efficiency at high ...
