    LT1976/LT1976B
    High Voltage 1.5A, 200kHz
    Step-Down Switching Regulator
    with 100μA Quiescent Current
    U FEATURES DESCRIPTIO ■ The LT®1976/LT1976B are 200kHz monolithic step-down
    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. 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 (LT1976) ...
