The LTC1475CMS8#PBF from Linear Technology is a versatile DC-DC converter supporting Buck, Buck-Boost, and SEPIC topologies. It operates from a 3V to 18V input and delivers up to 750mA of switch current. The output voltage is adjustable from 1.23V upward, making it suitable for a wide range of applications. Housed in a compact 8-MSOP package, it is ideal for portable, automotive, and industrial systems where board space is at a premium. Its flexible topology support allows designers to use a single part across multiple designs.
- Topology Flexibility: Supports Buck, Buck-Boost, and SEPIC configurations, allowing one part to be used in multiple applications.
- Wide Input Range: Operates from 3V to 18V, covering a broad spectrum of battery and industrial supply voltages.
- Compact Package: The 8-MSOP package is ideal for space-constrained designs.
- Low Parts Count: Requires minimal external components, simplifying design and reducing BOM cost.
Battery-Powered Equipment
With a 3V to 18V input range, the LTC1475 can operate from a wide variety of battery configurations, including 2-cell Li-Ion or multi-cell alkaline. Its buck-boost and SEPIC capabilities allow for a regulated output even when the battery voltage crosses the output voltage.
Portable Instruments
For handheld meters and test equipment, the LTC1475 provides a compact solution. The 8-MSOP package and minimal external components make it ideal for space-constrained designs requiring a stable 3.3V or 5V rail.
Automotive Auxiliary Power
In automotive systems, the LTC1475 can step down a 12V battery bus to power sensors, microcontrollers, or communication modules. Its wide input range handles cold-crank and load-dump transients.
Industrial Sensors
Industrial sensors often operate from 24V rails. The LTC1475 can buck this down to a lower logic voltage, providing a clean, regulated supply for signal conditioning and digital interfaces.
SEPIC for Positive-to-Positive Conversion
When configured as a SEPIC, the LTC1475 can generate a regulated output from an input that may be above or below the output, using a single inductor and coupling capacitor. This is useful in battery-powered devices where the battery voltage varies widely.
