The LTC1682CS8-5#PBF is a charge pump DC-DC converter from Analog Devices that delivers 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 small external capacitors. The 8-SOIC package is ideal for compact portable electronics. Typical applications include battery-powered devices, sensor bias supplies, and flash memory programming.
- Regulated 5V Output: Provides a stable rail from low-voltage batteries, eliminating the need for a separate boost stage.
- High Switching Frequency (550kHz): Allows the use of small ceramic capacitors, reducing PCB footprint.
- Wide Input Range (1.8V-4.4V): Compatible with single-cell Li-Ion and 2-cell alkaline batteries.
- Low Noise Operation: Charge pump topology minimizes conducted and radiated EMI for sensitive analog circuits.
Battery-Powered Portable Devices
Generate a stable 5V rail from a single-cell Li-Ion or 2-cell alkaline battery (1.8V-4.4V input). The 550kHz charge pump architecture minimizes external component size, ideal for space-constrained designs.
Flash Memory Programming
Provide the precise 5V programming voltage required for EEPROM and NOR flash devices. The low-noise regulated output ensures reliable write operations without additional LDOs.
Sensor Bias Supplies
Power precision analog sensors and op-amps that require a clean 5V supply. The charge pump's low EMI profile is suitable for sensitive measurement circuits.
Portable Medical Monitors
Generate a regulated 5V rail for glucose meters, pulse oximeters, and other handheld medical devices. The 50mA output is sufficient for low-power microcontrollers and displays.
White LED Backlight Drivers
Drive small white LED strings in portable displays. The regulated 5V output can be used with current-limiting resistors for consistent brightness.
Industrial Handheld Terminals
Power barcode scanners and handheld data terminals from a 2-cell battery pack. The charge pump's high efficiency extends battery life in intermittent-use scenarios.
