The LT1767EMS8E-1.8 is a versatile current-mode step-down DC-DC converter from Analog Devices, engineered to deliver a fixed 1.8V output from a wide 3V to 25V input supply. Capable of sourcing up to 1.5A, this regulator operates at a fixed 1.25MHz switching frequency, enabling the use of tiny, low-profile external components. Its high efficiency and ability to also function in SEPIC topology make it a robust solution for automotive, industrial, and portable applications where board space and thermal performance are critical.
- Wide Input Voltage Range (3V to 25V): Provides flexibility for various power sources, from multi-cell batteries to unregulated 12V/24V rails, ensuring reliable operation across diverse conditions.
- High Switching Frequency (1.25MHz): Allows for the use of small inductors and capacitors, significantly reducing the PCB footprint and overall solution size.
- SEPIC Topology Support: Offers design flexibility to generate a regulated output even when the input voltage is above or below the output, ideal for battery applications.
- 1.5A Output Current: Sufficient for powering a wide range of loads, including microprocessors, FPGAs, and peripheral logic circuits.
- Exposed Pad Package: The 8-MSOP/TSSOP package with exposed pad enhances thermal dissipation, improving reliability in high-temperature environments.
Battery-Powered Industrial Equipment
With a wide 3V to 25V input range and high efficiency, the LT1767EMS8E-1.8 is ideal for industrial handheld devices powered by multi-cell batteries, ensuring stable 1.8V logic rails as the battery voltage depletes.
Automotive Power Distribution
Automotive systems experience voltage transients. The LT1767's 25V maximum input safely handles load-dump conditions, providing a regulated 1.8V supply for microcontrollers and sensors in engine control units.
Distributed Power Systems
In systems with a 12V or 24V backplane, this buck converter efficiently steps down to 1.8V for local point-of-load regulation, reducing I2R losses and improving overall system efficiency.
SEPIC for Battery Charging
The SEPIC capability allows the converter to regulate a 1.8V output even when the input voltage is above or below the output, useful in applications with wide battery voltage variations.
Telecom and Networking Equipment
Operating from a 5V or 12V rail, the LT1767 provides a clean, low-noise 1.8V supply for high-speed DSPs and FPGAs, with the 1.25MHz frequency enabling a compact power supply design.
Portable Instrumentation
The high switching frequency reduces the size of inductors and capacitors, making the LT1767EMS8E-1.8 perfect for space-constrained portable test and measurement equipment requiring a precise 1.8V core supply.
