Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2673T-5.0/NOPB

LM2673T-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2673T-5.0/NOPB is a step-down switching regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with a fixed 5 V output and delivers up to 3 A of output current. The device utilizes a buck topology with an internal switch rated for high efficiency. It supports input voltages ranging from 8 V to 40 V. The component features a 260 kHz switching frequency and includes adjustable current limiting. It is housed in a TO-220-7 through-hole package and functions within a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a power switch and control circuitry into a single monolithic IC
Includes adjustable current limit protection for overload safety
Operates at a fixed 260 kHz switching frequency
Provides thermal shutdown protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for digital logic circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the ordering suffix /NOPB confirms compliance with RoHS standards and absence of hazardous substances. Confirm the manufacturer designation as Texas Instruments, noting that National Semiconductor was acquired by TI. Ensure the physical package matches the TO-220-7 specification for through-hole mounting requirements in your design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required with up to 3 A load capability. It is suitable for applications where a 260 kHz switching frequency allows for moderate-sized external inductors and capacitors. Consider the TO-220-7 package if thermal dissipation benefits from through-hole mounting are needed compared to surface-mount alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2673 series of SIMPLE SWITCHER regulators. It is functionally related to other variants such as the LM2673T-ADJ/NOPB for adjustable outputs or the LM2673SD-5.0/NOPB which uses a smaller DFN package. The series is characterized by its simplicity, requiring minimal external components for operation.
