LM2672N-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2672N-3.3/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator in an 8-pin MDIP package. It accepts input voltages from 8V to 40V and provides a fixed 3.3V output at up to 1A. Operating with a switching frequency of 260kHz, it achieves efficiencies up to 94%. The device integrates a 0.5A internal switch and supports operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a 0.5A power switch for simplified external component requirements
Includes internal frequency compensation to minimize external parts count
Features thermal shutdown protection for enhanced reliability

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment requiring efficient step-down conversion
Industrial control system power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free status and RoHS compliance. Confirm the 'N' designation indicates the through-hole MDIP package variant rather than surface-mount options. Ensure the '-3.3' code matches the required fixed output voltage specification for the target circuit design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a through-hole solution is preferred over surface-mount packages like SOIC or MSOP. It is suitable for applications requiring a fixed 3.3V output from higher bus voltages up to 40V. Consider alternative models if adjustable output or synchronous rectification is required.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2672 series of SIMPLE SWITCHER regulators. It shares core topology with surface-mount variants such as the LM2672M and LM2672MX but utilizes a Multi-Dual In-Line Package (MDIP) for through-hole mounting. The series is characterized by high efficiency and minimal external component counts.
