    ■ DESCRIPTIO The LTC®3252 is a switched capacitor step-down DC/DC
    converter that produces two adjustable regulated outputs
    from a single 2.7V to 5.5V input. The part uses switched
    capacitor fractional conversion to achieve a typical efficiency increase of 50% over that of a linear regulator. No
    inductors are required. 2.7V to 5.5V Input Voltage Range
    No Inductors
    Typical Efficiency 50% Higher than LDOs
    Spread Spectrum Operation ...

    DESIGN IDEAS Inductorless, Efficient Step-Down
    DC/DC Converter Provides Dual
    Low Noise Outputs in Spaceby Bill Walter
    Constrained Designs
    Introduction Increase Battery Run Time Linear Technology’s new LTC3252
    switched capacitor step-down DC/
    DC converter squeezes dual adjustable outputs into a space saving 3mm
    by 4mm DFN package. Each output is
    programmable within a range of 0.9V
    to 1.6V, is capable of 250mA of current, and operates from a single 2.7V
    to 5.5V supply. To keep the converter
    footprint small, the LTC3252 operates
    at high frequency, allowing the use of
    tiny low cost ceramic capacitors—no
    inductors are required. The LTC3252 also features Burst
    Mode® operation, which allows the
    LTC3252 to achieve high efficiency
    even with lightly loaded outputs. While
    in Burst Mode operation the LTC3252
    delivers a minimum amount of charge
    for a few cycles then goes into a low
    current state until the output drops
    enough to require another burst of ...
