The LT1173CS8-5 is a versatile, low-power DC-DC converter from Analog Devices, designed for both step-up (boost) and step-down (buck) applications. It operates from a wide 2V to 30V input supply and delivers a fixed 5V output. The internal 1.5A switch enables efficient power conversion at a low 23kHz switching frequency, minimizing electromagnetic interference. This makes it an excellent choice for battery-powered devices, industrial controls, and automotive systems where a stable, noise-free 5V rail is required. Its compact 8-SOIC package fits easily into space-constrained designs.
- Wide Input Flexibility: Operates from 2V to 30V, accommodating diverse power sources from batteries to industrial rails.
- Low EMI Operation: The 23kHz switching frequency reduces high-frequency noise, making it ideal for sensitive analog and RF circuits.
- High Efficiency: The internal 1.5A switch and optimized architecture ensure efficient conversion, extending battery life in portable applications.
- Design Versatility: Supports both buck and boost topologies, allowing a single part to be used in multiple power supply designs.
Battery-Powered Portable Devices
With a wide 2V to 30V input range and high efficiency, the LT1173CS8-5 is ideal for extending battery life in portable instruments, handheld meters, and remote sensors. Its low 23kHz switching frequency minimizes EMI, which is critical for sensitive analog measurement circuits.
5V Logic and Microcontroller Supplies
This fixed 5V output version is perfect for powering 5V logic, microcontrollers, and peripheral ICs from a variety of input sources, including 2-cell batteries or unregulated wall adapters. The internal 1.5A switch provides sufficient current for most logic loads.
Automotive and Industrial Systems
The wide input voltage range (up to 30V) makes it robust for automotive and industrial environments where supply rails can fluctuate significantly. It can efficiently step down 12V or 24V rails to a stable 5V for sensors, actuators, and control electronics.
Telecom and Networking Equipment
In networking gear, the LT1173CS8-5 can generate a clean 5V rail from a higher intermediate bus voltage. Its low-noise operation at 23kHz is advantageous in communication systems where high-frequency switching noise could interfere with data integrity.
Standalone Step-Up/Step-Down Regulator
As a flexible building block, it can be used in designs requiring either a boost or buck topology. This allows engineers to standardize on one part for multiple projects, simplifying inventory and reducing design time.
