LM2672N-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2672N-5.0 is a monolithic integrated DC-DC converter manufactured by Texas Instruments using LMDMOS technology. It functions as a step-down (buck) switching regulator capable of driving a 1A load current with excellent line and load regulation. The device operates within an input voltage range of 8V to 40V and provides a fixed 5.0V output. It incorporates an internal 260kHz oscillator, eliminating the need for external frequency compensation. Key electrical parameters include a maximum efficiency of 96%, a quiescent supply current of 2.5mA, and an operating temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates all active functions for a complete step-down switching regulator solution
• Requires only five external components for operation due to patented internal frequency compensation
• Features TTL shutdown capability for low-power standby modes
• Includes built-in thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in distributed power systems
• Pre-regulator stages for linear post-regulators
• Battery-powered equipment requiring efficient voltage conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'N' corresponds to the PDIP-8 through-hole package variant rather than surface-mount options. Confirm the '-5.0' designation indicates the fixed 5.0V output version. Check RoHS compliance status, as older revisions may differ from current NOPB equivalents. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a through-hole PDIP-8 package is required for prototyping or specific mechanical constraints. It is suitable for applications needing a fixed 5V output at up to 1A. Consider the LM2672M-ADJ if adjustable output or surface-mount packaging is preferred. Evaluate thermal management requirements based on the copper trace area needed for heat dissipation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the SIMPLE SWITCHER® family of high-efficiency step-down regulators. It shares architectural similarities with the LM2674 and LM2675 series but offers lower current capacity compared to higher-current variants like the LM2676. The device represents a standard solution for general-purpose voltage conversion tasks in industrial and consumer electronics.
