LT1944-1 Overview
Key Features
- 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
- Both converters feature a quiescent current of only 20µA at no load, which further reduces to 0.5µA in shutdown
- A current limited, fixed offtime 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
