    LT1374
    4.5A, 500kHz Step-Down
    Switching Regulator
    U FEATURES DESCRIPTIO ■ The LT ®1374 is a 500kHz monolithic buck mode switching
    regulator. A 4.5A switch is included on the die along with
    all the necessary oscillator, control and logic circuitry. High
    switching frequency allows a considerable reduction in the
    size of external components. The topology is current mode
    for fast transient response and good loop stability. Both
    fixed output voltage and adjustable parts are available. ■






    ■ Constant 500kHz Switching Frequency
    High Power 16-Pin TSSOP Package Available
    Uses All Surface Mount Components
    Inductor Size Reduced to 1.8µH
    Saturating Switch Design: 0.07Ω
    Effective Supply Current: 2.5mA
    Shutdown Current: 20µA ...
