The LT1944EMS#PBF is a dual micropower step-up DC/DC Converter with up to 34V high output voltage. Each converter is designed with a 350mA current limit and an input voltage range of 1.2 to 15V, making the LT1944 ideal for a wide variety of applications. It features 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 in a simple boost topology without the use of costly transformers. The LT1944"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.
● Uses small surface mount components
● 20µA Low quiescent current in active mode
● 1µA Low quiescent current in shutdown mode
