The LTC1682IMS8-5 is a low-noise charge pump DC-DC converter from Analog Devices that delivers a fixed 5V output from a 1.8V to 4.4V input. It supports up to 50mA of output current with a switching frequency of 550kHz, allowing for small external capacitors. The device is available in a compact 8-TSSOP or 8-MSOP package, making it suitable for space-constrained portable and battery-powered applications. Its high efficiency and low quiescent current extend battery life in handheld devices, while the regulated output ensures stable performance for sensors, displays, and auxiliary rails.
- Fixed 5V Output Simplifies Design: No external feedback resistors needed, reducing component count and design time.
- Wide Input Range (1.8V-4.4V): Compatible with single-cell Li-Ion, alkaline, or NiMH batteries, offering flexibility in power source selection.
- 550kHz Switching Frequency: Enables the use of small ceramic capacitors, minimizing PCB footprint and cost.
- Low Noise Operation: Charge pump topology with constant frequency reduces EMI, ideal for sensitive analog circuits.
- Compact Package Options: Available in 8-MSOP and 8-TSSOP, suitable for miniaturized portable designs.
Battery-Powered Portable Devices
The LTC1682IMS8-5 efficiently generates a regulated 5V rail from a 1.8V to 4.4V battery source, making it ideal for powering sensors, displays, and small peripherals in handheld instruments and wearable devices.
Biasing for LCD Displays
Many small LCD panels require a stable 5V bias supply. This charge pump provides a low-noise, fixed 5V output from a single lithium-ion cell, ensuring consistent display performance.
Local 5V Rail Generation
In systems with a 3.3V main supply, the LTC1682IMS8-5 can generate a local 5V rail for legacy ICs, level shifters, or small motors without requiring an additional inductor, saving board space.
Remote Sensor Power
For remote or isolated sensor nodes powered by two alkaline cells (1.8V-3V), this device boosts to a stable 5V, enabling reliable operation of analog front-ends and wireless transceivers.
Memory Backup Supplies
The 50mA output is sufficient to power SRAM or RTC backup circuits at 5V, maintaining data integrity during main power loss with minimal quiescent current.
Industrial Control I/O
In industrial control panels, the charge pump can provide a clean 5V supply for optocouplers, relays, or digital isolators from a 3.3V logic rail, simplifying power distribution.
