The LT1767EMS8E-3.3 is a high-performance current mode step-down DC-DC converter from Analog Devices, designed to deliver a fixed 3.3V output. It operates from a wide 3V to 25V input supply and provides up to 1.5A of output current. With a 1.25MHz switching frequency, it enables the use of small, low-profile inductors and capacitors, making it ideal for space-constrained applications. Its high efficiency and low quiescent current extend battery life in portable electronics. The converter is available in a compact 8-lead MSOP package with exposed pad for excellent thermal performance. Typical applications include battery-powered instruments, automotive systems, industrial controls, and distributed power architectures.
- Wide Input Voltage Range (3V to 25V): Provides flexibility for various power sources, including multi-cell batteries and automotive rails.
- High Switching Frequency (1.25MHz): Allows for smaller external components, reducing overall solution size and board space.
- 1.5A Output Current: Sufficient for powering a wide range of loads, from microcontrollers to small FPGAs.
- Fixed 3.3V Output: Simplifies design for common logic and I/O voltage rails, eliminating the need for external resistor dividers.
- SEPIC Capability: Offers design flexibility for applications requiring a non-inverting output that can be above or below the input.
Battery-Powered Portable Devices
With a wide 3V to 25V input range and high 1.25MHz switching frequency, this converter efficiently regulates 3.3V rails in battery-powered equipment, minimizing board space with small external components.
Automotive Power Supplies
The LT1767EMS8E-3.3 handles automotive battery transients up to 25V, providing a stable 3.3V output for sensors, microcontrollers, and CAN transceivers in engine control units and infotainment systems.
Industrial Control Systems
Its 1.5A output current capability and robust design make it suitable for powering industrial sensors, PLC I/O modules, and fieldbus communication interfaces from 12V or 24V supply rails.
