The LT1767EMS8#TRPBF is a versatile 1.5A step-down DC-DC converter from Analog Devices, designed for a wide range of applications. It operates from an input voltage of 3V to 25V and provides an adjustable output from 1.2V to 22.5V. The fixed 1.25MHz switching frequency allows for small, low-cost external components while maintaining high efficiency. It can also be configured as a SEPIC converter for applications requiring a flexible input-to-output relationship. The compact 8-lead MSOP package makes it suitable for space-constrained designs.
- Wide Input Range (3V to 25V): Supports a variety of power sources, from single-cell batteries to 24V industrial rails.
- 1.5A Output Current: Provides ample current for a wide range of loads, including processors and sensors.
- Fixed 1.25MHz Switching Frequency: Simplifies EMI filtering and allows for small inductors and capacitors.
- SEPIC Capability: Offers design flexibility for applications where the output voltage may be higher or lower than the input.
- Compact MSOP Package: Saves board space in portable and space-limited applications.
Portable Electronics
With a 3V to 25V input range, the LT1767EMS8#TRPBF can be powered from a single Li-Ion cell or a 12V adapter. Its 1.5A output is ideal for powering processors, displays, and memory in handheld devices, while the 1.25MHz frequency allows for small external components.
SEPIC Topology for Battery-Powered Systems
When configured as a SEPIC converter, this device can regulate an output voltage that is higher, lower, or equal to the input. This is useful in applications where the battery voltage varies widely, such as in portable instruments powered by multiple cells.
Networking and Communication
In routers and switches, the LT1767EMS8#TRPBF can step down a 5V or 12V rail to power PHYs, FPGAs, and control logic. The fixed 1.25MHz switching frequency simplifies filtering and reduces electromagnetic interference (EMI).
Industrial Control Systems
For industrial sensors and actuators, this buck converter provides a stable low-voltage supply from a 24V bus. Its wide input range ensures operation during voltage sags and surges, improving system reliability.
Automotive Accessories
In automotive infotainment and telematics, the device can regulate power from the 12V battery to 5V or 3.3V for microcontrollers and GPS modules. The 1.5A current capability is sufficient for most accessory loads.
Distributed Power Supplies
In systems with multiple voltage rails, the LT1767EMS8#TRPBF can be used as a post-regulator to generate a clean, low-noise supply from a noisy intermediate bus, improving overall system performance.
