The LT1372HVIS8 from Linear Technology is a highly versatile current-mode switching regulator. It supports multiple topologies including Buck, Boost, Cuk, Flyback, Forward, and SEPIC, operating from a 2.7V to 30V input. The internal 1.5A switch and fixed 500kHz frequency allow for compact, efficient power conversion. Its high-voltage capability makes it suitable for automotive and industrial applications, while its low input voltage supports battery-powered devices. The 8-lead SOIC package ensures easy integration into a wide range of designs.
- Topology Flexibility: Supports Buck, Boost, Cuk, Flyback, Forward, and SEPIC, reducing design risk and part count across multiple projects.
- Wide Input Range: Operates from 2.7V to 30V, accommodating various battery chemistries and automotive transients.
- Compact Solution: The 500kHz switching frequency allows for small external components, saving board space.
- High-Voltage Switch: The 1.5A, 42V switch enables higher output voltages in boost and flyback configurations.
Multi-Topology Power Supplies
The LT1372HVIS8's ability to support Buck, Boost, and SEPIC topologies makes it a flexible solution for prototyping and low-volume production where multiple output voltages are needed from a single design.
Battery-Powered Equipment
With a low 2.7V minimum input, it can operate from a single-cell Li-Ion or multi-cell alkaline battery stack, efficiently boosting to 3.3V, 5V, or 12V rails for portable instruments.
Automotive Power Systems
The wide 30V input capability allows it to handle load-dump and cold-crank conditions in 12V automotive systems, providing regulated power for sensors and control modules.
Isolated Flyback Supplies
In industrial and telecom settings, the flyback configuration provides a simple, cost-effective way to generate isolated output voltages for gate drivers or communication interfaces.
Negative Output Generation (Cuk)
The Cuk topology enables the generation of a negative rail from a positive input, which is essential for powering op-amps and analog circuits in test and measurement equipment.
High-Frequency Compact Designs
The 500kHz switching frequency reduces the size of the inductor and capacitors, enabling compact power supply designs for space-constrained applications.
