LM2673T-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2673T-5.0/NOPB is a step-down switching regulator from Texas Instruments operating at a fixed frequency of 260 kHz. It provides a fixed output voltage of 5 V with a maximum output current capability of 3 A. The device accepts an input voltage range from 8 V to 40 V and utilizes a buck topology. It is housed in a TO-220-7 through-hole package, designed for high efficiency and integrated thermal protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch rated for 3 A continuous load current
• Fixed internal feedback network for simplified design
• Built-in thermal shutdown circuitry for overload protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for digital logic circuits
• Pre-regulation for downstream linear regulators
• Battery-powered systems requiring efficient voltage conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB indicates lead-free and RoHS compliance. Confirm the 'T' designation corresponds to the TO-220-7 through-hole package variant rather than surface-mount options. Ensure the '-5.0' suffix matches the required 5 V fixed output specification for the target application.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from an 8 V to 40 V input source. It is suitable for applications needing up to 3 A of output current where a through-hole mounting solution is preferred. Consider the 260 kHz switching frequency for inductor size trade-offs compared to higher-frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2673 SIMPLE SWITCHER family of monolithic step-down converters. The series includes adjustable versions (ADJ) and other fixed voltage outputs. The TO-220 package variant distinguishes it from surface-mount counterparts like the LM2673S or LM2673SD.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2673T-5.0/NOPB serves as a direct replacement for earlier non-NOPB variants within the same package. For different current ratings, consider the LM2677 series for 5 A output or the LM2679 series for enhanced performance.
