LT3483IDC(V2) Datasheet PDF - Linear Technology

DESCRIPTION
The LT®3483 is a micropower inverting DC/DC converter 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 device features 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 loading of the output.
