High Output Voltage: Up to – 34V
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 20 μ A at no load, which further
reduces to 0.5 μ A in shutdown. A current limited, fixed off-
time control scheme conserves operating current, result-

ing 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.
