Product Overview

The LT1944-1EMS#PBF is a dual micropower step-up DC/DC Converter with 1.5µs OFF-time. One converter is designed with a 100mA current limit and a 400ns OFF-time, the other with a 175mA current limit and a 1.5µs OFF-time. The 1.5µs OFF-time converter is ideal for generating an output voltage that is close to the input voltage (i.e. a LiIon to 5V converter or a two-cell to 3.3V converter). With an input voltage range of 1.2 to 15V, the LT1944-1 is 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. Tiny, low profile inductors and capacitors can be used 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
