    12-Pin (3mm × 4mm) DFN Packages The LTC®3245 is a switched capacitor buck-boost DC/DC
    converter that produces a regulated output (3.3V, 5V or
    adjustable) from a 2.7V to 38V input. The device uses
    switched capacitor fractional conversion to maintain
    regulation over a wide range of input voltage. Internal
    circuitry automatically selects the conversion ratio to
    optimize efficiency as input voltage and load conditions ...
