The LT1373HVIN8 is a highly versatile monolithic DC-DC converter from Analog Devices, designed for a broad spectrum of power conversion needs. Its flexible architecture supports Buck, Boost, Cuk, Flyback, Forward, and SEPIC topologies, making it a single-chip solution for many design challenges. Operating from a 2.7V to 30V input, it can deliver up to 1.5A of switch current. The fixed 250kHz switching frequency allows for small, low-profile external components. This combination of flexibility and power makes it suitable for applications ranging from industrial control systems to portable battery-powered devices.
- Maximum Design Flexibility: Supports six different topologies (Buck, Boost, Cuk, Flyback, Forward, SEPIC) in one IC, reducing inventory and design time.
- Wide Input Voltage Range: Operates from 2.7V to 30V, accommodating a wide range of power sources including batteries and industrial rails.
- High-Voltage Output Capability: Can generate output voltages up to 42V (switch limit), suitable for bias supplies and other high-voltage applications.
- Robust 1.5A Switch: The integrated high-current switch enables power levels suitable for a wide range of medium-power applications.
Battery-Powered Industrial Equipment
With a wide 2.7V to 30V input range, the LT1373HVIN8 efficiently regulates power from multi-cell batteries or unregulated wall adapters, ensuring stable operation as the battery voltage depletes.
Automotive Power Systems
Its ability to handle up to 30V input makes it robust for 12V automotive environments, where load-dump transients can create voltage spikes. The high-voltage rating provides a safety margin for such conditions.
Isolated Flyback Converters
The integrated 1.5A switch and flyback topology support the creation of isolated power supplies for industrial sensors and communication interfaces, providing galvanic isolation to prevent ground loops.
Negative Output Voltage Generation
Using the Cuk or inverting topology, the LT1373HVIN8 can generate a negative rail from a positive input, which is essential for powering op-amps and other analog circuits in test and measurement equipment.
SEPIC Converters for Variable Inputs
In SEPIC configuration, this IC can maintain a regulated output even when the input voltage is above, below, or equal to the output. This is ideal for portable devices powered by a variety of sources.
High-Voltage Bias Supplies
The ability to set the output up to 42V (switch limit) allows for generating high-voltage bias rails for MEMS devices, PIN diodes, or LCD displays from a low-voltage logic supply.
