LT1316CS8#TRPBF

Overview

The LT1316CS8#TRPBF is a monolithic switching regulator featuring an integrated high-voltage power switch. It operates as a step-down (buck) converter with programmable peak current limiting and adjustable frequency control. The device supports input voltages up to 40V and delivers output currents determined by external components. It includes internal compensation, soft-start functionality, and thermal shutdown protection. Packaged in an 8-lead SOIC for surface mount applications, it provides efficient DC/DC conversion in compact designs.

Feature Summary

• Integrates a high-voltage power switch for simplified circuit design
• Features programmable peak current limiting for robust overload protection
• Includes internal frequency compensation to reduce external component count
• Provides adjustable switching frequency for optimized efficiency and size

Applications

• Point-of-load regulation in industrial equipment
• Battery-powered systems requiring efficient voltage step-down
• General-purpose DC/DC conversion in embedded electronics

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm the manufacturer part number matches Analog Devices Inc. specifications exactly. Check for RoHS compliance documentation if required by your assembly process. Ensure the package type aligns with your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when a high-voltage input range up to 40V is required alongside integrated power switching. Consider the adjustable frequency feature for noise management or efficiency optimization. Evaluate the thermal performance under expected load conditions given the SOIC-8 package constraints. Compare against other buck regulators if lower input voltage or higher current density is needed.

Part Context

This part belongs to the LT1316 family of switching regulators from Analog Devices. It is designed for applications needing a reliable, high-voltage buck converter solution. The CS8 variant indicates a commercial temperature range and SOIC-8 package. It serves as a cost-effective alternative to discrete solutions while maintaining performance in space-constrained environments.

Replacement Considerations

Consult official Analog Devices substitution guides for verified equivalents. Cross-reference pinouts and electrical characteristics carefully. Ensure any substitute maintains the 40V input rating and similar switching frequency ranges.
