Inverting Micropower  
DC/DC Converters  
with Schottky  
FEATURES  
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

Low Quiescent Current:  
size as small as 40mm . The devices feature a quiescent  
40µA in Active Mode  
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.
