The LTC1682IS8-3.3 from Analog Devices is a low-noise, switched-capacitor voltage doubler that provides a regulated 3.3V output. It operates from an input voltage between 1.8V and 4.4V and delivers up to 50mA of output current. The 550kHz switching frequency allows for the use of small, low-cost external capacitors. Its simple design requires no inductors, making it an ideal solution for space-constrained, low-power applications such as battery-powered devices and sensor interfaces.
- No Inductor Required: The charge pump topology uses only capacitors, simplifying design and reducing electromagnetic interference (EMI).
- Low Output Noise: Provides a clean, regulated 3.3V supply, suitable for powering sensitive analog and RF circuits.
- Wide Input Range (1.8V to 4.4V): Operates from a variety of battery chemistries and configurations, including single Li-Ion cells.
- Compact and Simple: Requires only a few external capacitors, minimizing board space and total bill of materials.
