    High Efficiency, 15V Rail-to-Rail Output Synchronous
    Step-Down Regulator Can Source or Sink 5A
    Timothy Kozono The LTC3623 is a high efficiency, monolithic synchronous step-down regulator capable of
    sourcing or sinking up to 5A of continuous output current from an input voltage range of
    4V to 15V. Its compact 3mm Г— 5mm QFN package incorporates an abundance of features
    including a low EMI Silent Switcher architecture, output voltage cable drop compensation
    and single resistor output voltage programming. The constant frequency/controlled
    on-time architecture responds quickly to line and load transients even in low duty cycle,
    high frequency applications. The device offers a 400kHz to 4MHz operating frequency
    range with multiple optional protection and monitoring features, enabling compact, robust
    solutions. VIN regulation, discontinuous/continuous mode and a supply current less than
    1ВµA during shutdown make this regulator suitable for a wide range of power applications.
    A single resistor is used to set the internal reference voltage for the device. The
    adjustable internal reference voltage
    sets the output voltage and allows the
    outputВ voltage to operate rail-to-rail,
    from 0V to VIN . The reference voltage
    can be driven directly as an audio
    driver or configured to operate as a
    TEC driver. Capable of sourcing or
    sinking 5A of output current, the regulator moves the output voltage quickly
    in either direction. The output
    current monitor signal can be used ...
