    LT1977
    High Voltage 1.5A, 500kHz
    Step-Down Switching Regulator
    with 100µA Quiescent Current
    U FEATURES DESCRIPTIO ■ The LT®1977 is a 500kHz monolithic buck switching
    regulator that accepts 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. Current mode topology is used for fast transient
    response and good loop stability. ■










    ■ Wide Input Range: 3.3V to 60V
    1.5A Peak Switch Current
    Burst Mode® Operation: 100µA Quiescent Current**
    Low Shutdown Current: IQ < 1µA ...
