DESCRIPTIO

The LT

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

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 loading of the output. The

40V switch enables voltage outputs up to –38V to be

generated without the use of costly transformers. The

LT3483’s low 300ns off-time permits the use of tiny low

profile inductors and capacitors to minimize footprint and

cost in space-conscious portable applications.

The LT3483 is available in the low profile (1mm) SOT-23
