The LTC1928ES6-5 is a low-noise, inductorless charge pump DC-DC converter from Analog Devices, designed to provide a regulated 5V output from a 2.7V to 4.4V input. It delivers up to 30mA of output current with a switching frequency of 550kHz. The charge pump topology eliminates the need for an inductor, resulting in a very compact and low-EMI power solution. Housed in a tiny SOT-23-6 package, it is ideal for space-constrained, battery-powered applications such as medical devices, portable instruments, and memory programming circuits.
- Inductorless Operation: The charge pump design requires no inductor, reducing EMI and simplifying the power supply design.
- Compact Footprint: The small SOT-23-6 package and minimal external components (only a few capacitors) save significant board space.
- Low Noise Output: Provides a clean 5V rail, making it suitable for powering sensitive analog circuits.
- Simple Fixed Output: The fixed 5V output eliminates the need for external feedback resistors, simplifying the BOM.
Low-Power 5V Rail Generation
The LTC1928ES6-5 is ideal for generating a regulated 5V rail from a 2.7V to 4.4V input, such as a single lithium-ion battery. Its charge pump topology requires no inductors, reducing EMI and solution size.
Battery-Powered Medical Devices
For portable medical monitors and glucose meters, this charge pump provides a clean, low-noise 5V supply for analog front-ends and sensors, ensuring accurate readings while maintaining a small footprint.
EEPROM and Memory Programming
Many EEPROMs and flash memories require a 5V programming voltage. The LTC1928ES6-5 can provide this from a lower system voltage, simplifying power supply design in embedded systems.
Operational Amplifier Supply
In single-supply systems, the 5V output can be used to power operational amplifiers and other analog ICs that need a stable, higher voltage rail for improved dynamic range.
Portable Instrumentation
The low quiescent current and high efficiency of the charge pump make it suitable for battery-powered instruments where extending battery life is critical, such as handheld multimeters and data loggers.
