The LTC1515CS8-3/5 is a charge pump DC-DC converter from Analog Devices, offering a pin-selectable 3V or 5V output from a wide 2V to 10V input. It delivers up to 50mA at a fixed 650kHz switching frequency, enabling the use of tiny ceramic capacitors. This inductorless design minimizes EMI and component count, making it an excellent choice for battery-powered devices, industrial sensors, and mixed-voltage logic systems.
- No Inductor Required: Eliminates inductor selection and layout concerns, reducing design time.
- Wide Operating Range: 2V to 10V input supports diverse power sources.
- Stable Fixed Frequency: 650kHz switching allows predictable filtering and small capacitors.
- Dual Output Options: 3V or 5V selection increases application flexibility.
Battery-Powered Handheld Tools
Generate a stable 3V or 5V rail from a 2V-10V battery pack. The charge pump's high frequency allows for small external components, keeping the tool lightweight.
5V Rail for Analog Circuits
Provide a low-noise 5V supply for op-amps and ADCs from a 3.3V digital rail, avoiding the heat dissipation of a linear regulator.
3V Logic from 5V System
Step down a 5V logic supply to 3V for legacy microcontrollers or memory, maintaining compatibility without a separate regulator IC.
Industrial Process Control
With a wide input range, it can operate from 24V industrial rails (via a simple pre-regulator) to provide a local 5V for sensors and transceivers.
Portable Test Equipment
Use the selectable output to power different sections of a multimeter or scope probe, simplifying power architecture.
Automotive Sensor Modules
In 12V automotive systems, the wide input tolerance handles transients, providing a regulated 5V for Hall-effect sensors or pressure transducers.
