Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2673S-ADJ

LM2673S-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2673S-ADJ/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator in a TO-263 package. It operates with an input voltage range of 8V to 40V and delivers up to 3A output current. The adjustable output voltage spans from 1.2V to 37V. Key electrical parameters include a switching frequency of 260kHz, a maximum efficiency of 88%, and a junction temperature operating range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic power switch for simplified design
Internal frequency compensation reduces external component count
Built-in thermal shutdown protection safeguards against overheating

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 indicates lead-free RoHS compliance. Confirm the S suffix corresponds to the TO-263 surface mount package. Ensure the ADJ designation matches the requirement for an adjustable output voltage configuration rather than a fixed voltage variant.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 40V and continuous load current of 3A are required. The adjustable output feature allows flexibility for various target voltages. Consider the TO-263 package for adequate thermal dissipation in high-current applications without additional heatsinking.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2673 series of SIMPLE SWITCHER regulators. It shares core topology and performance characteristics with other variants in the family, such as the LM2673T-ADJ (TO-220) and LM2673SD-5.0 (DFN), differing primarily in package type and output voltage options.
