The LT1373CS8 is a versatile current-mode DC-DC converter from Analog Devices, supporting Buck, Boost, Cuk, Flyback, Forward, and SEPIC topologies. It operates from an input voltage of 2.7V to 30V, with a 1.5A switch current and output adjustable from 1.245V to 35V. The fixed 250kHz switching frequency allows small external components while maintaining high efficiency. Packaged in an 8-pin SOIC, it is ideal for automotive, industrial, and telecom applications requiring flexible voltage conversion from a single IC.
- Six Topologies in One IC: Reduces design risk and part count across multiple product lines.
- Wide Input Range (2.7V-30V): Handles automotive and industrial supply variations without external regulators.
- 1.5A Switch Current: Supports up to 15W output power in boost mode, suitable for sensors and actuators.
- 250kHz Fixed Frequency: Balances efficiency and component size, with predictable EMI for filtering.
Multi-Rail Industrial Power
The LT1373CS8's ability to configure as buck or boost from a 5V to 30V input allows a single design to generate 3.3V, 5V, or 12V rails for PLCs and industrial sensors, reducing inventory.
Automotive Infotainment
With a 30V input rating, it can step down from a 12V car battery (with load dump transients) to power audio codecs and display drivers, while the 250kHz frequency avoids AM radio interference.
Telecom Line Driver Supplies
As a Cuk converter, it can produce a negative rail from a positive 5V or 12V supply for op-amp-based line drivers in DSL and cable modems.
Battery-Powered Handheld Tools
Operating from a 2.7V to 10V battery pack, the boost configuration provides a regulated 12V for motor drivers and solenoid actuators in cordless tools.
Isolated Flyback for Gate Drivers
Using a flyback transformer, the LT1373CS8 generates isolated 15V supplies for IGBT/SiC gate drivers in motor drives, with 1.5A switch current supporting high dv/dt transients.
Solar-Powered Irrigation Controllers
In remote agricultural systems, the SEPIC topology allows a varying solar panel voltage (5V-25V) to charge a 12V battery while maintaining MPPT operation.
