The LTC1682IMS8-3.3 is a fixed 3.3V output charge pump DC-DC converter from Analog Devices. It accepts an input voltage from 1.8V to 4.4V and delivers up to 50mA of output current. The 550kHz switching frequency enables the use of small external capacitors, and the device is available in an 8-TSSOP or 8-MSOP package. This converter is well-suited for battery-powered applications requiring a regulated 3.3V rail, such as microcontrollers, sensors, and wireless modules. Its low-noise operation and high efficiency help maximize battery life in portable designs.

  • Fixed 3.3V Output: Eliminates external feedback components, simplifying PCB layout and reducing BOM.
  • Wide Input Range (1.8V-4.4V): Works with single-cell Li-Ion, alkaline, or NiMH batteries.
  • 550kHz Switching Frequency: Allows for small ceramic capacitors, saving board space.
  • Low Noise: Constant frequency operation minimizes EMI, suitable for sensitive analog loads.
  • Compact 8-MSOP/TSSOP Package: Ideal for space-constrained portable devices.
