The LTC1682IMS8 is a versatile charge pump DC-DC converter from Analog Devices, offering an adjustable output from 2.5V to 5.5V. It operates from a 1.8V to 4.4V input and delivers up to 50mA of output current. The 550kHz switching frequency allows for small external components, and the device is housed in an 8-TSSOP or 8-MSOP package. This converter is ideal for battery-powered devices, sensor biasing, and mixed-signal systems where a tunable voltage rail is required. Its low-noise operation and high efficiency make it a reliable choice for space-constrained designs.
- Adjustable Output (2.5V-5.5V): Provides design flexibility for various load requirements without changing the IC.
- Wide Input Range (1.8V-4.4V): Supports multiple battery chemistries and single-cell Li-Ion applications.
- 550kHz Switching Frequency: Allows for tiny ceramic capacitors, reducing board space and BOM cost.
- Low Quiescent Current: Extends battery life in always-on portable devices.
- Compact Package: 8-MSOP/TSSOP footprint fits into miniaturized designs.
