Description
General part information
LT3463 Series
The LT3463/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. The 42V switch enables high voltage outputs up to ±40V to be easily generated without the use of costly transformers. The low 300ns offtime permits the use of tiny, low profile inductors and capacitors to minimize footprint and cost in space-conscious portable applications.ApplicationsCCD BiasLCD BiasHandheld ComputersDigital Cameras
