LT1945IMS#PBF

LINEAR TECHNOLOGY  LT1945IMS#PBF  芯片, 直流/直流转换器, 双路, 34V, -34V, 0.35A, 10MSOP

The is a dual micropower DC/DC Converter designed with a 350mA current limit and an input voltage range of 1.2 to 15V, making the LT1945 ideal for a wide variety of applications. Both converters feature a quiescent current of only 20µA at no load, which further reduces to 0.5µA 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 36V switch allows high voltage outputs up to ±34V to be easily generated without the use of costly transformers. The LT1945"s low OFF-time of 400ns permits the use of tiny, low profile inductors and capacitors to minimize footprint and cost in space-conscious portable applications.
