The LTC1682CS8 from Analog Devices is a versatile charge pump DC-DC converter with an adjustable output from 2.5V to 5.5V. Operating from a 1.8V to 4.4V input, it delivers up to 50mA at a 550kHz switching frequency. Its adjustable nature makes it suitable for a wide range of battery-powered applications where different voltage rails are needed, including IoT devices, portable instruments, and display biasing circuits.
- Adjustable Output: Set any voltage from 2.5V to 5.5V with external resistors, providing design flexibility for multiple applications.
- Wide Input Range: Operates from 1.8V to 4.4V, compatible with single-cell Li-ion, alkaline, or NiMH batteries.
- High-Frequency Operation: 550kHz switching allows for small external capacitors, saving board space.
- Low Quiescent Current: Optimized for battery-powered devices, extending operational life.
Adjustable Supply for Variable Logic Levels
With an adjustable 2.5V-5.5V output, the LTC1682CS8 can power different logic families (LVCMOS, LVTTL) from a single 1.8V-4.4V input, simplifying multi-voltage board designs.
Battery-Powered IoT Sensors
IoT nodes often need different voltages for MCU, radio, and sensors. This charge pump provides a flexible, efficient boost solution from a single Li-ion or alkaline cell, extending battery life.
Portable Instrumentation
Handheld multimeters or field calibrators can use the adjustable output to generate reference voltages or bias supplies, with the 550kHz frequency keeping external components small.
Biasing for Displays and Backlights
Small LCD or OLED displays may require a specific bias voltage. The LTC1682CS8 can be trimmed to the exact voltage needed, improving display contrast and performance.
Audio CODEC Power Supplies
Audio codecs often need a clean, adjustable supply for analog and digital sections. This charge pump provides a low-noise rail that can be optimized for the specific codec requirements.
Prototyping and Lab Equipment
As a flexible building block, the LTC1682CS8 allows engineers to quickly prototype different voltage rails without redesigning the power section, accelerating development cycles.
