The LTC1522CS8 is a charge pump DC-DC converter from Linear Technology that delivers a regulated 5V output from a 2.7V to 5V input. It supports up to 20mA of output current and operates at a fixed 700kHz switching frequency, enabling the use of tiny external capacitors. Housed in a compact 8-SOIC package, it is well-suited for battery-powered and space-constrained applications requiring a stable 5V rail.
- Compact Solution: The 700kHz switching frequency allows for small external capacitors, reducing PCB footprint.
- Regulated 5V Output: Provides a stable 5V rail even as the input voltage varies between 2.7V and 5V.
- Low Noise: Charge pump topology offers low electromagnetic interference for sensitive analog circuits.
- Simple Design: Requires minimal external components, simplifying the overall power supply design.
Battery-Powered Portable Devices
Generate a stable 5V rail from a 2.7V to 5V battery source. The 700kHz switching frequency allows for small external capacitors, minimizing board space in compact designs.
Flash Memory Programming
Provide the precise 5V supply needed for programming and erasing flash memory in embedded systems. The low output current requirement (20mA) is ideal for this application.
Sensor Bias Supplies
Power analog sensors or op-amps requiring a clean 5V bias from a lower voltage logic supply. The charge pump topology ensures low noise operation.
Portable Instrumentation
Use in handheld meters or test equipment where a regulated 5V is needed for LCD displays or analog front-ends, while maintaining high efficiency across the input range.
Remote Low-Power Modules
Power wireless transmitters or microcontrollers in remote sensors. The small SOIC package and minimal external components simplify the PCB layout.
