The LT1372CN8 is a highly versatile DC-DC converter IC from Analog Devices, supporting Buck, Boost, Cuk, Flyback, Forward, and SEPIC topologies. It operates from an input voltage of 2.7V to 30V and features a 1.5A switch with a 35V rating. The fixed 500kHz switching frequency allows for small external components. This flexibility makes it ideal for a wide range of applications, from automotive power supplies to isolated flyback converters and battery-powered systems.
- Multi-Topology Support: One IC replaces multiple dedicated converters, reducing inventory and design time.
- Wide Input Range (2.7V-30V): Handles automotive, industrial, and battery voltage variations.
- 1.5A Switch with 35V Rating: Supports moderate power levels in flyback and boost applications.
- Through-Hole 8-DIP Package: Easy to prototype and solder, ideal for breadboard and hobbyist designs.
Multi-Topology Power Supplies
The LT1372CN8's flexibility to operate as Buck, Boost, SEPIC, or Flyback makes it a single solution for prototyping and low-volume production where multiple output voltages are needed from varying input sources.
Flyback Converters for Isolated Supplies
Its 1.5A switch and 35V rating enable compact flyback designs for isolated 5V/12V supplies in industrial control and telecom applications, eliminating the need for a separate controller.
Automotive 12V Systems
With a 30V input range, it can step down 12V automotive rails to 5V for sensors or step up to 24V for actuator drivers, handling load transients effectively.
Battery-Powered Equipment
For 3-6 cell NiMH or Li-ion packs (3.6V-25V), this converter can boost or buck to maintain a regulated output as the battery voltage changes.
Negative Output (Cuk) Converters
The Cuk topology capability allows generation of a negative rail (e.g., -5V) from a positive input, useful for op-amp supplies in analog signal processing.
