The LTC1682CS8-3.3 from Linear Technology is a charge pump step-up converter that provides a fixed 3.3V output from a 1.8V to 4.4V input. It delivers up to 50mA with a 550kHz switching frequency. The 8-SOIC package offers a compact, inductor-free solution for battery-powered applications.
- Low Input Voltage: Starts from 1.8V, compatible with single-cell Li-ion or two alkaline batteries.
- Fixed 3.3V Output: Simplifies design for standard logic and sensor power.
- No Inductor: Charge pump topology reduces EMI and external component count.
- 550kHz Switching: Allows for small capacitors, minimizing PCB footprint.
