The LT1767EMS8-5 from Linear Technology is a versatile 1.5A Buck converter with a fixed 5V output. It accepts a wide input voltage from 3V to 25V, making it suitable for automotive, industrial, and telecom applications. The 1.25MHz switching frequency allows for small external components and low output ripple. Its ability to operate in SEPIC topology adds flexibility for systems where the input can fall below the output voltage. The compact 8-MSOP package is ideal for space-limited designs.
- Wide Input Range: 3V to 25V covers automotive and industrial power sources with ample margin.
- SEPIC Capability: Supports step-up/step-down operation, maintaining a regulated 5V output even with fluctuating inputs.
- High Frequency: 1.25MHz switching reduces inductor size and improves transient response.
- Fixed 5V Output: Simplifies design for standard 5V logic and analog rails without external resistor dividers.
Automotive Power Supplies
The 3V to 25V input range handles wide battery voltage variations, providing a regulated 5V rail for sensors, ECUs, and infotainment systems.
Industrial 24V Systems
It efficiently steps down 24V industrial supplies to 5V for microcontrollers, op-amps, and interface circuits in factory automation and process control.
Telecom and Networking
With 1.25MHz switching, it can filter EMI easily, making it suitable for 5V rails in telecom base stations and networking switches powered from 12V or 24V buses.
SEPIC Topology for Battery Backup
The SEPIC capability allows the output to remain regulated at 5V even when the input drops below 5V, ideal for systems with battery backup or wide input swings.
Portable Instruments
Operating from 3V to 25V, it can be powered by a variety of sources (2-cell Li-ion, 12V adapters) while delivering a stable 5V for precision analog circuits.
Distributed Power Architectures
As a local 5V POL converter, it provides clean, regulated power from a higher-voltage intermediate bus, reducing noise coupling in mixed-signal systems.
