Description

General part information

LT1944-1 Series

The LT1944-1 is a dual micropower step-up DC/DC converter in a 10-pin MSOP package. 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 Li-Ion to 5V converter, or a two-cell to 3.3V converter). With an input voltage range of 1.2V to 15V, the LT1944-1 is 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. Tiny, low profile inductors and capacitors can be used to minimize footprint and cost in space-conscious portable applications.Switch CurrentLT1944350mA, 350mALT1944-1100mA, 175mAApplicationsSmall TFT LCD PanelsHandheld ComputersBattery BackupDigital Cameras
