    ■ DESCRIPTIO The LT ®1956/LT1956-5 are 500kHz monolithic buck
    switching regulators with an input voltage capability 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 architecture provides fast transient response and good loop stability. Wide Input Range: 5.5V to 60V
    1.5A Peak Switch Current
    Small 16-Pin SSOP or Thermally Enhanced
    TSSOP Package
    Saturating Switch Design: 0.2Ω ...
