    LT8614
    42V, 4A Synchronous
    Step-Down Silent Switcher
    with 2.5µA Quiescent Current
    DESCRIPTION FEATURES Silent Switcher™ Architecture: Ultralow EMI/EMC Emissions
    n High Efficiency at High Frequency Up to 96% Efficiency at 1MHz Up to 94% Efficiency at 2MHz
    n Wide Input Voltage Range: 3.4V to 42V
    n Ultralow Quiescent Current Burst Mode® Operation: 2.5μA IQ Regulating 12VIN to 3.3VOUT Output Ripple < 10mVP-P
    n Fast Minimum Switch-On Time: 30ns
    n Low Dropout Under All Conditions: 200mV at 1A
    n Safely Tolerates Inductor Saturation in Overload
    n Adjustable and Synchronizable: 200kHz to 3MHz
    n Peak Current Mode Operatio Accurate 1V Enable Pin Threshold
    n Internal Compensatio Output Soft-Start and Tracking
    n Small 18-Lead 3mm × 4mm QFN
    n APPLICATIONS Automotive and Industrial Supplies General Purpose Step-Dow GSM Power Supplies The LT®8614 step-down regulator features Silent Switcher
    architecture designed to minimize EMI/EMC emissions
    while delivering high efficiency at frequencies up to 3MHz.
    Assembled in a 3mm × 4mm QFN, the monolithic construction with integrated power switches and inclusion of all
    necessary circuitry yields a solution with a minimal PCB
    footprint. An ultralow 2.5µA quiescent current—with the
    output in full regulation— enables applications requiring
    highest efficiency at very small load currents. Transient ...
