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 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.
