LM2676S-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2676S-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER power module integrating a 3A step-down switching regulator in a TO-263-7 package. It operates with an input voltage range of 8V to 40V and provides a fixed 5V output. The device features a 260kHz switching frequency, 88% efficiency, and a maximum junction temperature of 125°C. It includes internal current limiting and thermal shutdown for protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates controller, switch, diode, and freewheeling components into a single module
Includes internal current limit and thermal shutdown protection
Requires minimal external component count for implementation

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment power supplies
General-purpose 5V distribution networks

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance status. Confirm the 'S' designation matches the required TO-263-7 surface-mount package variant. Ensure the '-5.0' identifier aligns with the specific 5V fixed output requirement for the target circuit design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a compact solution is needed for 3A loads with inputs up to 40V. The integrated topology reduces board space compared to discrete designs. Verify that the 260kHz frequency meets EMI requirements and that the TO-263-7 package fits the thermal constraints of the application.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2676 family of SIMPLE SWITCHER regulators. It shares functional similarities with the LM2679 (5A) and LM2677 (1A) variants but is distinct in its 3A current rating. The series is designed for high-efficiency buck conversion with simplified design processes.
