FEATURES
s s DESCRIPTIO s s s s s s Generates Well-Regulated Positive and Negative Outputs Low Quiescent Current: 20µA (per Converter) in Active Mode <1µA in Shutdown Mode Internal 42V Power Switches Internal 42V Schottky Diodes Low VCESAT Switch: 180mV at 150mA Input Voltage Range: 2.4V to 15V High Output Voltages: Up to ±40V Low Profile (0.8mm) 3mm x 3mm DFN Package U APPLICATIO S s s s s CCD Bias LCD Bias Handheld Computers Digital Cameras The LT®3463/LT3463A are dual micropower DC/DC converters with internal Schottky diodes in a 10-lead 3mm × 3mm DFN package. Negative and positive LT3463 converters have a 250mA current limit. The LT3463A positive converter also has a 250mA limit, while the negative converter has a 400mA limit. Both devices have an input voltage range of 2.4V to 15V, making them ideal for a wide variety of applications. Each converter features a quiescent current of only 20µA, which drops to under 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.
