    60V Current Mode
    Synchronous Step-Up Controller
    FEATURES DESCRIPTION
    The LTC3814-5 is a synchronous step-up switching regulator controller that can generate output voltages up to
    60V. The LTC3814-5 uses a constant off-time peak current
    control architecture to deliver very high duty cycles with
    accurate cycle-by-cycle current limit without requiring a
    sense resistor. High Output Voltages: Up to 60V
    Large 1Ω Gate Drivers
    No Current Sense Resistor Required
    Dual N-Channel MOSFET Synchronous Drive
    ±0.5% 0.8V Voltage Reference
    Fast Transient Response
    Programmable Soft-Start
    Generates 5.5V Driver Supply
    Power Good Output Voltage Monitor
    Adjustable Off-Time/Frequency: tOFF(MIN) < 100ns
    Adjustable Cycle-by-Cycle Current Limit
    Undervoltage Lockout On Driver Supply
    Output Overvoltage Protection
    Thermally Enhanced 16-Pin TSSOP Package A precise internal reference provides ±0.5% DC accuracy.
    A high bandwidth (25MHz) error amplifier provides very ...
