The LT1376CS8 is a high-efficiency step-down DC-DC converter from Analog Devices. It integrates a 1.5A power switch and operates from an input voltage range of 5V to 25V. The output is adjustable from 2.42V to 21.5V, providing flexibility for various applications. With a fixed 500kHz switching frequency, it allows for small external components, reducing board space. It can also be configured as a SEPIC converter for applications where the input voltage may be above or below the output. The 8-SOIC package makes it easy to integrate into a wide range of designs.
- High Switching Frequency: The fixed 500kHz operation allows for smaller inductors and capacitors, reducing the overall solution footprint.
- Versatile Topologies: Can be used as a buck or SEPIC converter, providing design flexibility for various input/output voltage combinations.
- Wide Output Range: The adjustable output from 2.42V to 21.5V covers many common voltage rails.
- Integrated Switch: The 1.5A switch reduces external component count and simplifies the PCB layout.
5V to 3.3V Point-of-Load
The LT1376CS8 is well-suited for converting a 5V supply rail down to 3.3V for logic circuits, FPGAs, or microcontrollers. Its 500kHz fixed frequency allows for small, low-profile inductors and capacitors.
12V to 5V Industrial Supply
In industrial control systems, this regulator can efficiently step down a 12V bus to a regulated 5V rail for sensors, op-amps, and digital logic. The 1.5A switch current is sufficient for many auxiliary loads.
SEPIC for Wide Input Range
When configured as a SEPIC, the LT1376CS8 can produce a regulated output even when the input voltage varies above or below the output. This is useful in automotive applications where the battery voltage can sag during cranking.
Negative Output Supply
The LT1376 can be used in an inverting topology to generate a negative voltage rail from a positive input, which is often needed for op-amp or audio circuits.
Battery-Powered Equipment
For devices operating from a 12V lead-acid battery, the LT1376's high efficiency helps reduce heat and extend battery life, making it suitable for portable instruments and communication equipment.
