The LT1767EMS8E is a versatile current mode DC-DC converter from Analog Devices, designed for Buck and SEPIC topologies. It operates from a 3V to 25V input, delivering up to 1.5A of output current. With a fixed 1.25MHz switching frequency, it enables the use of tiny external components, resulting in a compact power solution. The output voltage is adjustable from 1.2V to 22.5V, making it suitable for a wide range of applications, including battery-powered devices, industrial controls, and automotive systems. Its high efficiency and robust design ensure reliable performance in demanding environments.
- High Efficiency: Current mode architecture and low dropout operation maximize efficiency, extending battery life in portable applications.
- Compact Solution Size: The 1.25MHz switching frequency allows for small inductors and capacitors, reducing the overall PCB footprint.
- Wide Input Voltage Range: Operates from 3V to 25V, accommodating a variety of power sources including multi-cell batteries and industrial rails.
- Design Flexibility: Supports both Buck and SEPIC configurations, providing a single IC solution for step-down or inverting/step-up/down needs.
Battery-Powered Portable Devices
With a wide 3V to 25V input range and high 1.25MHz switching frequency, the LT1767EMS8E is ideal for portable devices where battery voltage varies. The high frequency allows for small, low-profile inductors and capacitors, saving critical board space in compact designs.
SEPIC Converters for Regulated Rails
When configured as a SEPIC converter, this IC can generate a regulated output voltage that is either higher or lower than the input. This is particularly useful in automotive and industrial systems where the supply voltage can fluctuate above or below the desired output rail.
Distributed Power Systems
The 1.5A output current capability and 25V maximum input make it suitable for point-of-load (POL) conversions in distributed power architectures, providing a clean, regulated local supply from a higher-voltage bus.
Industrial Control and Instrumentation
Its robust 25V input rating and stable current-mode control ensure reliable operation in industrial environments with noisy or varying supply lines, powering sensors, microcontrollers, and analog circuitry.
Networking and Telecom Equipment
The high switching frequency minimizes the solution footprint, which is critical in densely packed networking hardware. The LT1767EMS8E can efficiently step down 12V or 24V rails to power logic and interface circuits.
Automotive Power Supplies
Handling input transients up to 25V, this converter is well-suited for automotive applications, powering infotainment systems, sensors, and control units directly from the car battery or a pre-regulated supply.
