The LTC1682CMS8-5 is a low-noise, regulated charge pump DC-DC converter that produces a fixed 5V output from a 1.8V to 4.4V input. It delivers up to 50mA of output current, making it ideal for battery-powered applications. The 550kHz switching frequency allows for the use of small, low-cost ceramic capacitors. This device requires no inductors, reducing EMI and simplifying the design. It is an excellent choice for generating a clean 5V rail in portable, medical, and IoT devices where space and efficiency are critical.
- No Inductor Required: The charge pump topology eliminates the need for an inductor, reducing EMI and simplifying PCB layout.
- Low Input Voltage Operation: Operates from as low as 1.8V, allowing use with single-cell batteries down to their end-of-life voltage.
- Small Solution Size: The 8-MSOP package and tiny ceramic capacitors result in a very compact power supply solution.
- Regulated 5V Output: Provides a stable 5V rail even as the battery voltage declines, ensuring consistent performance of the load.
Battery-Powered 5V Rails
Generates a regulated 5V supply from a single Li-Ion cell (2.7V-4.2V) or two alkaline batteries (1.8V-3V). The 50mA output is ideal for powering low-power sensors, op-amps, and small microcontrollers.
Flash Memory Programming
Provides the 5V programming voltage for EEPROMs and flash memory in portable devices. The low-noise, regulated output ensures reliable write operations without additional external components.
Portable Medical Devices
Powers glucose monitors, hearing aids, and wearable health trackers from a single coin cell. The 550kHz charge pump allows for tiny external capacitors, minimizing the overall solution footprint.
Wireless Sensors and IoT
Supplies a stable 5V rail for RF transceivers, sensors, and microcontrollers in battery-operated IoT nodes. The high efficiency of the charge pump extends battery life in duty-cycled applications.
LCD Bias Supplies
Provides the 5V bias voltage for small LCD displays in handheld instruments and consumer electronics. The low quiescent current and small package make it ideal for space-constrained designs.
