The LT1372HVIN8 is a high-frequency, multi-topology DC-DC converter from Analog Devices. It is designed for applications where board space is at a premium, thanks to its 500kHz switching frequency which minimizes the size of external components. Like its counterpart, it supports Buck, Boost, Cuk, Flyback, Forward, and SEPIC topologies. It operates from a 2.7V to 30V input and features a 1.5A switch. This makes it an excellent choice for compact, efficient power solutions in automotive, industrial, and portable applications.
- Small Solution Footprint: The 500kHz switching frequency significantly reduces the size of external inductors and capacitors, saving valuable PCB space.
- Multi-Topology Versatility: Supports Buck, Boost, Cuk, Flyback, Forward, and SEPIC, providing a single flexible solution for various power conversion needs.
- Wide Input Voltage Range: Operates from 2.7V to 30V, making it suitable for a wide range of battery and industrial power sources.
- High Switching Frequency: Enables faster transient response and smaller output ripple compared to lower frequency converters.
Compact Power Supplies for Portable Devices
The 500kHz switching frequency of the LT1372HVIN8 allows for the use of smaller inductors and capacitors, enabling compact power supply designs for handheld instruments and portable electronics.
Automotive Sensor Interfaces
With a wide 2.7V to 30V input range, it can be directly powered from a 12V automotive bus, providing a stable regulated supply for sensors and microcontrollers despite battery voltage fluctuations.
Industrial Control Loops
In Boost or SEPIC configurations, it can generate higher voltage rails for industrial actuators, relays, and valve drivers from a stable 24V or 12V control supply.
Isolated Power for Data Acquisition
Using a Flyback topology, the LT1372HVIN8 can create isolated, low-noise power supplies for analog front-ends in data acquisition systems, preventing ground noise from corrupting sensitive measurements.
Negative Rail Generation for Audio
The Cuk topology enables the generation of a clean negative supply rail from a positive input, which is critical for powering high-performance operational amplifiers in audio equipment.
Multi-Output Bias Supplies
By using multiple windings on a flyback transformer, this single IC can generate multiple isolated output voltages, simplifying the power architecture for complex systems.
