Overview
The LT1176CSW-5#PBF is a monolithic switching regulator from Analog Devices, housed in a 20-lead SOIC (Wide) package. It integrates a 1A power switch, oscillator, and control circuitry for buck applications. The device supports fixed 5V output configurations with input voltage ranges up to 42V. Operating temperature spans 0°C to 70°C. It features current mode control for rapid transient response and includes internal soft-start functionality.
Feature Summary
- Integrates high-current power switch and control logic for simplified design
- Supports flexible positive or negative output voltage configurations
- Includes internal soft-start to limit inrush current during startup
Applications
- Point-of-load regulation in distributed power systems
- Industrial equipment power supplies
- Telecommunications infrastructure
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the wide SOIC package matches your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet revision notes before finalizing procurement specifications.
Selection Notes
Select this component when a robust, integrated solution is required for step-down conversion without external MOSFETs. The wide SOIC package facilitates thermal management and assembly compared to smaller footprints. Consider the fixed 5V output variant if standard logic levels are needed, ensuring input voltages remain within the specified operational limits.
Part Context
This part belongs to the LT1176 family of switching regulators, designed for high-reliability applications requiring minimal external components. The CSW designation indicates the commercial temperature range and wide SOIC package style. The -5 suffix specifies the fixed 5V output version, distinguishing it from adjustable variants within the same product line.
Replacement Considerations
LT1176CSW#PBF serves as the adjustable counterpart to this fixed-output variant. Verify compatibility if substituting with other Buck regulators, ensuring equivalent current handling and package dimensions match the existing design constraints.
