    Docket ↓
    60V Current Mode
    Synchronous Step-Up Controller
    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 1О© Gate Drivers
    No Current Sense Resistor Required
    Dual N-Channel MOSFET Synchronous Drive
    В±0.5% 0.8V Voltage Reference

    Synchronous Boost Converters Provide High Voltage without the Heat
    Docket ↓
    DESIGN FEATURES L Synchronous Boost Converters Provide
    High Voltage without the Heat
    by Greg Dittmer Introduction
    The LTC3813 and LTC3814-5 reduce
    the size of high voltage, high power
    boost converters by incorporating
    heat-saving features that eliminate
    the need for large components and
    heat sinks. In particular, two features
    significantly reduce heat losses over
    other high power boost solutions:
    q Synchronous control eliminates
    the high power loss in the diode
    at high output currents
    q Strong internal gate drivers
    reduce switching losses at high
    output voltages.
    The LTC3813 can regulate output voltages up to 100V, while the LTC3814-5 is suitable for applications
    up to 60V. They both use a constant
    off-time peak current mode control
    architecture. Current mode control
    provides tight cycle-by-cycle monitoring of inductor current and constant
    off-time allows high conversion ratios ...
