LM2674N-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2674N-5.0/NOPB is a Texas Instruments fixed-output step-down switching regulator designed for through-hole mounting in an MDIP-8 package. It delivers a maximum output current of 500mA with a fixed 5V output voltage. The device operates from an input voltage range of 8V to 40V and features a switching frequency of up to 275kHz. It achieves an efficiency of 90% and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic buck converter topology for efficient voltage reduction
Fixed 5V output configuration eliminating external feedback resistor networks
Through-hole MDIP-8 packaging suitable for standard PCB layouts

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for digital logic circuits
Power supply stages for microcontroller systems
General-purpose DC-DC conversion in industrial control panels

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance. Confirm the N designation corresponds to the MDIP-8 through-hole package variant rather than surface-mount options. Ensure the -5.0 suffix matches the required 5V fixed output specification for the target design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust through-hole solution is required for 5V generation from higher bus voltages. The 500mA current limit suits low-power digital loads. Consider thermal dissipation requirements due to the lack of an exposed pad compared to surface-mount equivalents.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2674 family of SIMPLE SWITCHER regulators. It shares functional similarities with the LM2574 series but offers optimized performance characteristics. The device integrates the power switch, controller, and freewheeling diode into a single monolithic IC.
