The LT1373HVCS8 is a versatile 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 42V. The fixed 250kHz switching frequency provides a good balance between efficiency and component size. Packaged in an 8-SOIC, it is suitable for portable, industrial, and automotive power applications.
- Multi-Topology Support: Buck, Boost, Cuk, Flyback, Forward, and SEPIC in one device, maximizing design flexibility.
- Wide Input Range: 2.7V to 30V covers battery, 5V, 12V, and 24V systems.
- High Voltage Output: Up to 42V switch rating enables boost and flyback applications.
- Fixed 250kHz Frequency: Simplifies EMI filtering and allows small external components.
- Compact SOIC-8 Package: Ideal for space-constrained designs with minimal external parts.
Portable Battery Chargers
With a 2.7V minimum input, the LT1373HVCS8 can boost a single-cell battery to charge higher-voltage batteries or power LED flash circuits in cameras and portable devices.
Industrial Sensor Power
In 24V industrial systems, this converter steps down to 5V or 3.3V for sensors, transmitters, and microcontrollers, with the 250kHz frequency reducing filter size.
Automotive Electronics
The 30V input rating handles automotive transients, making it suitable for powering ECUs, infotainment, and lighting from 12V batteries.
Negative Voltage Generation
Using the Cuk or buck-boost topology, it can generate negative rails (e.g., -5V) for op-amps, audio circuits, and LCD bias supplies.
Isolated Flyback Supplies
For low-power isolated supplies in telecom and industrial applications, the flyback topology with a 1.5A switch provides a simple, cost-effective solution.
SEPIC Converters
When input voltage can be above or below the output, the SEPIC topology allows non-inverting regulation, ideal for automotive and battery applications with wide voltage swings.
