The LT1767EMS8-2.5 is a versatile current mode DC-DC converter from Analog Devices, designed for Buck and SEPIC topologies. It accepts a wide input voltage from 3V to 25V and delivers a fixed 2.5V output at up to 1.5A. The 1.25MHz fixed switching frequency enables the use of tiny external components, reducing board space. Its high efficiency and low dropout make it ideal for battery-powered, automotive, and industrial applications requiring a stable, compact power solution.
- Wide Input Range (3V-25V): Handles unregulated supplies and battery voltage variations without external pre-regulation.
- High Switching Frequency (1.25MHz): Enables small inductors and capacitors, reducing PCB footprint and cost.
- 1.5A Output Current: Sufficient for powering FPGAs, DSPs, and sensors in demanding applications.
- Buck and SEPIC Support: Provides design flexibility for step-down or inverting/step-up/step-down topologies.
Battery-Powered Industrial Sensors
With a wide 3V to 25V input range and 1.5A output capability, this converter efficiently regulates 2.5V from multi-cell batteries or unregulated supplies, extending battery life in remote monitoring systems.
Automotive Infotainment Power
The 1.25MHz fixed frequency allows for small, low-profile inductors and capacitors, saving PCB space in space-constrained automotive head units while handling load transients from 12V rails.
SEPIC for Point-of-Load Regulation
When configured as a SEPIC, the LT1767 can step up or down from a varying input, providing a stable 2.5V rail for sensors in industrial control systems where input voltage fluctuates.
Portable Medical Devices
High efficiency at light loads and a low quiescent current make this suitable for battery-operated medical monitors, ensuring reliable 2.5V power for sensitive analog circuits.
Telecom Line Cards
Operating from a 5V or 12V backplane, the converter delivers 1.5A at 2.5V for DSPs and FPGAs, with the high frequency reducing output ripple and external component count.
Distributed Power Architectures
As an intermediate bus converter, it steps down 24V industrial rails to a local 2.5V bus, simplifying thermal management and improving overall system efficiency.
