The LT1767EMS8E-3.3#TRPBF is a high-frequency step-down DC-DC converter from Analog Devices. It accepts an input voltage from 3V to 25V and provides a fixed 3.3V output at up to 1.5A. Operating at 1.25MHz, it enables the use of small, low-cost inductors and capacitors, minimizing board space. The exposed pad package ensures excellent thermal performance. This converter is ideal for automotive, industrial, and distributed power systems requiring a compact, efficient 3.3V supply.
- High Efficiency: Internal synchronous rectification (if applicable) or low dropout design maximizes efficiency across load ranges.
- Wide Input Range: 3V to 25V input handles automotive transients and industrial supply variations.
- Small Solution Size: 1.25MHz switching frequency allows for tiny external components, saving PCB area.
- Thermally Enhanced Package: Exposed pad on MSOP-8 improves heat dissipation for reliable operation at 1.5A.
Distributed Power Systems
In telecom and networking equipment, the LT1767EMS8E-3.3 steps down a 12V or 24V bus to a regulated 3.3V logic rail, delivering 1.5A with high efficiency.
Automotive Electronics
With a wide 3V-25V input range, it handles load-dump and cold-crank conditions, providing a stable 3.3V supply for ECUs, sensors, and infotainment systems.
Industrial Control Boards
For PLCs and motor controllers, this buck converter generates a 3.3V MCU supply from a 24V industrial rail, with the 1.25MHz frequency allowing for small ceramic capacitors.
Battery-Powered Devices
In portable instruments, the high efficiency at light loads extends battery life, while the 3V minimum input supports operation from a single lithium cell down to its discharge cutoff.
