LM2673SDX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2673SDX-5.0/NOPB is a fixed-output buck switching regulator from Texas Instruments' SIMPLE SWITCHER family, housed in a 14-VSON package with exposed pad. It provides a regulated 5 V output at up to 3 A load current. The device operates from an input voltage range of 8 V to 40 V and switches at a frequency of 260 kHz. It features integrated current limiting and thermal shutdown for protection, functioning within a junction temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch eliminates the need for external components
• Fixed 5 V output simplifies design for standard logic supplies
• Built-in current limit and thermal shutdown ensure robust operation

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems

• Power supply stages for communication equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SDX' against the manufacturer's official datasheet to confirm it denotes the tape-and-reel packaging variant of the LM2673SD-5.0/NOPB. Ensure the ordering part number matches the exact package type and reel quantity required for your assembly process before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact surface-mount solution is required for 5 V generation from higher bus voltages. The 14-VSON package offers a smaller footprint compared to TO-263 or TO-220 alternatives while maintaining 3 A capability. Consider the 260 kHz switching frequency for balancing component size and efficiency requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2673 series of simple switcher regulators, designed for high-efficiency step-down conversion. It serves as a drop-in replacement for older linear regulators in applications requiring lower heat dissipation. The series is characterized by minimal external component count and ease of use for standard voltage rails.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2673SD-5.0/NOPB is the tube-packaged equivalent. Verify if the reel format is critical for automated placement. Other family members like LM2673S-5.0 offer different packages but similar electrical performance.
