DESCRIPTION
The LT ? 3483/LT3483A are micropower inverting DC/DC
converters with integrated Schottky and one resistor
feedback. The small package size, high level of integration
and use of tiny surface mount components yield a solution
size as small as 40mm 2 . The devices feature a quiescent
current of only 40μA at no load, which further reduces
to 0.1μA in shutdown. A current limited, fixed off-time
control scheme conserves operating current, resulting
in high efficiency over a broad range of load current. A
precisely trimmed 10μA feedback current enables one
resistor feedback and virtually eliminates feedback load-
ing of the output. The 40V switch enables voltage outputs
up to –38V to be generated without the use of costly
transformers. The LT3483/LT3483A’s low 300ns off-time
permits the use of tiny low profile inductors and capaci-
tors to minimize footprint and cost in space-conscious
portable applications.
