    design features 2.7V to 40V Monolithic Buck-Boost DC/DC Expands
    Input Capabilities, Regulates Seamlessly through
    Automotive Cold-Crank and Load-Dump Transients
    John Canfield Handheld devices, industrial instruments and automotive electronics all demand power
    supply solutions that can support an expansive range of input voltages resulting from
    automotive input voltage transients, resistive line drops and a wide variety of power
    sources. As a further design challenge, applications often require a variety of regulated
    voltage rails, including some that fall within the input voltage range. The LTC3115-1
    buck-boost DC/DC converter, with its wide 2.7V to 40V input and output voltage
    capability, high efficiency, small footprint and seamless transition between step-up and
    step-down modes of operation, easily meets the requirements of such applications.
    For automotive electronics, the LTC3115-1
    provides uninterrupted operation through
    load dump transients and even the harshest cold-crank conditions. Its programmable switching frequency optimizes
    efficiency and supports operation at 2MHz
    to ensure that switching noise and harmonics are located above the AM broadcast
    band. The LTC3115-1 employs a proprietary low noise PWM control algorithm
    that minimizes electromagnetic emissions over all operating conditions even
    during transitions between the step-up
    and step-down modes of operation and
    over the full range of load current. An
    internal phase-locked loop allows switching edges to be synchronized with an
    external clock for further control of ...
