The LT1372HVCN8 is a versatile, high-frequency switching regulator from Analog Devices. Its flexible architecture supports multiple topologies, including buck, boost, Cuk, flyback, forward, and SEPIC, making it a universal solution for a wide range of power conversion needs. It operates from a 2.7V to 30V input and features a 1.5A, 42V internal switch. The fixed 500kHz switching frequency allows for small external components. Housed in a robust 8-pin DIP package, it is well-suited for industrial, automotive, and high-voltage bias applications.
- Multi-Topology Flexibility: One IC can be used for buck, boost, or isolated flyback designs, reducing inventory and design time.
- Wide Input and Switch Voltage: Handles inputs up to 30V and switch voltages up to 42V, suitable for industrial and automotive rails.
- High Switching Frequency: The 500kHz operation minimizes the size of external inductors and capacitors.
- Robust 8-Pin DIP Package: Easy to prototype and use in through-hole PCB designs, ideal for industrial environments.
Industrial 24V Rail Conversion
In industrial control systems, a 24V DC bus is common. The LT1372HV's 30V input rating allows it to directly step down a 24V supply to a 5V or 3.3V logic rail using a buck topology, simplifying the power architecture and reducing heat dissipation compared to linear regulators.
Automotive Battery Regulation
Automotive electrical systems experience wide voltage swings, from cold-crank dips below 6V to load-dump spikes over 40V. The LT1372HV's 2.7V to 30V input range and 42V switch rating make it robust enough for many automotive applications, such as powering sensors, actuators, or display modules directly from the battery line.
Isolated Flyback Power Supply
For applications requiring galvanic isolation, such as industrial motor drives or medical equipment, the LT1372HV can be used in a flyback topology. Its 1.5A switch and 500kHz frequency allow for a compact transformer, enabling a small, isolated auxiliary power supply to be built with minimal components.
SEPIC for Wide-Ranging Inputs
In applications where the input voltage can be both above and below the output, such as in automotive or battery-powered systems, the LT1372HV can be configured as a SEPIC converter. This allows a regulated 5V output from an input that varies from, for example, 3V to 15V, without the complexity of a true buck-boost IC.
High-Voltage Bias Supply
The LT1372HV's 42V switch rating enables it to generate higher voltage rails, such as 24V or 36V, from a lower input voltage using a boost topology. This is useful for powering op-amps, LCD bias supplies, or industrial sensors that require a higher voltage than the main system rail.
