LX1732
Key Features
- C OM The LX1732 is a pact, high efficiency, step-up DC-DC boost regulator implemented in a BiCMOS process technology
- Start-up operation is guaranteed from 1.1V inputs (at light load) and the input voltage can be as low as 0.7V after start-up
- The output voltage programming range of 2.2V to 5V, requires only two external resistors via the feedback pin (see Figure 1.0)
- Output load currents of up to 200mA are achievable and the internal MOSFET is capable of switching up to a 1A current limit
- Quiescent current during operation is 200µA (max) and in shutdownmode drops to a mere 1µA thus maximizing overall battery lifetime
