The LTC1682IS8-5 is a low-noise charge pump DC-DC converter from Analog Devices, designed to deliver a regulated 5V output from a 1.8V to 4.4V input. It supports up to 50mA of output current with a switching frequency of 550kHz, enabling the use of small, low-cost capacitors. This fixed-output converter is ideal for battery-powered applications requiring a stable, clean voltage rail without the complexity of an inductor-based solution.
- Compact Solution: Charge pump topology eliminates the need for an inductor, reducing component count and board space.
- Low Noise Operation: The 550kHz switching frequency allows for small external capacitors and provides a clean output suitable for sensitive analog circuits.
- Wide Input Range: Operates from 1.8V to 4.4V, compatible with various battery chemistries.
- Regulated Fixed Output: Provides a precise 5V rail without external feedback resistors.
Battery-Powered Portable Devices
Generate a stable 5V rail from a single lithium-ion or 2-cell alkaline battery (1.8V-4.4V input) for sensors, op-amps, or small logic circuits. The 550kHz charge pump allows for small external capacitors, saving board space.
Biasing for LCD Displays
Provide a regulated 5V bias supply for small LCD panels in handheld instruments. The low 50mA output is sufficient for display drivers while maintaining a compact solution.
Flash Memory Programming
Supply the 5V programming voltage needed for EEPROM or flash memory devices in low-power embedded systems, directly from a lower system voltage.
Portable Medical Monitors
Create a clean, regulated 5V supply for analog front-ends in battery-operated medical devices. The charge pump topology minimizes electromagnetic interference compared to inductive converters.
Remote Sensor Nodes
Power wireless sensor nodes that require a 5V rail for signal conditioning from a 3.3V or lower battery source. The high efficiency of the charge pump extends battery life.
