LT3483IDC Datasheet PDF - Linear Technology

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 40mm2. 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.
