The LTC1682CMS8 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 with a 550kHz switching frequency. The adjustable output is set with two external resistors, providing design flexibility for various low-power applications. Housed in a compact 8-pin MSOP/TSSOP package, it is ideal for battery-powered instruments, sensor biasing, and portable audio circuits where efficiency and small size are paramount.
- Adjustable Output: Set any voltage from 2.5V to 5.5V with two resistors, offering design flexibility across multiple applications.
- Wide Input Compatibility: Operates from 1.8V to 4.4V, covering common battery chemistries without extra regulation.
- Low Ripple: The 550kHz fixed-frequency switching minimizes output noise, critical for analog and RF circuits.
- Minimal External Parts: Requires only two capacitors and two resistors, simplifying layout and reducing cost.
Adjustable Rail Generation
The adjustable output (2.5V to 5.5V) allows designers to set a custom voltage rail using two resistors, providing flexibility in mixed-voltage systems without changing the PCB layout.
Battery-Powered Instrumentation
With a 1.8V to 4.4V input, this charge pump efficiently powers portable multimeters or data loggers, delivering a stable adjustable output from a single-cell battery.
Biasing Circuits for RF Modules
The low-noise 550kHz operation makes it suitable for biasing RF switches or VCOs, where clean supply voltage is essential for maintaining signal integrity.
Sensor Excitation
For bridge sensors or thermocouple amplifiers requiring a precise 2.5V or 4.096V reference, the adjustable output provides a cost-effective solution with minimal external components.
Portable Audio Equipment
In battery-powered audio devices, the charge pump can generate a negative or higher positive rail for headphone amplifiers, improving dynamic range while maintaining efficiency.
