    ■ DESCRIPTIO The LT®1617/LT1617-1 are micropower inverting DC/DC
    converters in a 5-lead SOT-23 package. The LT1617 is
    designed for higher power systems with a 350mA current
    limit and an input voltage range of 1.2V to 15V, whereas
    the LT1617-1 is intended for lower power and single-cell
    applications with a 100mA current limit and an extended
    input voltage range of 1V to 15V. Otherwise, the two
    devices are functionally equivalent. Both devices feature a
    quiescent current of only 20µA at no load, which further
    reduces to 0.5µA in shutdown. A current limited, fixed offtime control scheme conserves operating current, resulting in high efficiency over a broad range of load current.
    The 36V switch allows high voltage outputs up to – 34V to
    be easily generated without the use of costly transformers.
    The LT1617’s low off-time of 400ns permits the use of
    tiny, low profile inductors and capacitors to minimize
    footprint and cost in space-conscious portable applications. Low Quiescent Current: ...
