The LT1767EMS8-3.3#PBF is a fixed 3.3V output step-down DC-DC converter from Analog Devices, capable of delivering up to 1.5A. It operates from an input voltage range of 3V to 25V, making it versatile for automotive, industrial, and battery-powered applications. The switching frequency is fixed at 1.25MHz, allowing for small, low-profile external components. Housed in a compact 8-MSOP package, it is an efficient solution for space-constrained designs requiring a regulated 3.3V rail.
- Fixed 3.3V Output: Simplifies design with no external feedback resistors needed.
- Wide Input Range (3V-25V): Suitable for multiple power sources, including batteries and industrial rails.
- 1.25MHz Fixed Frequency: Enables small external components, reducing board space.
- SEPIC Capability: Offers flexibility for input voltages above or below the output.
Automotive Audio Systems
The 25V input range handles 12V automotive systems, providing a clean 3.3V rail for audio DSPs and codecs with low noise.
Industrial Sensor Interfaces
For 24V industrial sensors, the LT1767 steps down to 3.3V for logic and communication interfaces, ensuring reliable operation.
Battery-Powered Equipment
With a 3V minimum input, it can operate from 2-cell alkaline or single Li-ion batteries, delivering a stable 3.3V for microcontrollers.
Networking Peripherals
Its fixed 1.25MHz frequency allows for small external components, making it suitable for compact network adapters and switches.
SEPIC Applications
When configured as a SEPIC, it can generate a 3.3V output from inputs above or below 3.3V, useful in battery backup systems.
