The LT1372CS8 is a highly flexible DC-DC converter from Analog Devices, supporting buck, boost, Cuk, flyback, forward, and SEPIC topologies. It operates from a 2.7V to 30V input and features a 1.5A internal switch, enabling output voltages up to 35V. With a fixed 500kHz switching frequency, it offers a good balance between efficiency and component size. This versatility makes it ideal for industrial, automotive, and portable power designs.
- Six Topologies in One Device: Reduces design effort and part count across multiple product lines.
- 1.5A Switch with 500kHz: Delivers adequate power for medium-load applications while keeping inductor size small.
- Wide Input Range (2.7V-30V): Suitable for both low-voltage battery and high-voltage industrial rails.
- Fixed Frequency Operation: Simplifies EMI filtering and ensures predictable noise performance.
Multi-Rail Industrial Power
The LT1372CS8's ability to be configured as a buck or boost converter allows a single design to generate both 5V and 12V rails from a 9V-18V industrial supply, reducing inventory complexity.
SEPIC for Wide-Range Input
In automotive or battery systems where input voltage can be above or below the output, the SEPIC topology provides a non-inverting regulated output without a transformer.
Isolated Flyback for Gate Drivers
The flyback configuration with a 1.5A switch can generate isolated +15V/-5V rails for IGBT or MOSFET gate drivers in motor control applications.
Negative Output (Cuk) for Op-Amps
The Cuk topology generates a clean negative rail (e.g., -5V) from a positive input, ideal for precision analog circuits requiring dual supplies.
Forward Converter for Medium Power
For applications needing higher efficiency than flyback at 5-10W, the forward converter topology with the LT1372CS8 provides a robust solution.
Battery-Powered Portable Equipment
With a 2.7V minimum input, it can boost from a 3V battery to 5V for USB-powered peripherals, while the 500kHz frequency allows small inductors.
