DESCRIPTION
The LT®1944-1 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 LiIon 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.
