Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2673SX-ADJ

LM2673SX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2673SX-ADJ/NOPB is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments, housed in a VSON-14 surface-mount package. It operates with an input voltage range of 8V to 40V and provides an adjustable output voltage between 1.2V and 37V. The device supports a maximum output current of 3A with a fixed switching frequency of 260kHz. It functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated power switch eliminates the need for external high-current components
Adjustable soft-start limits inrush current during startup
Built-in current limit protects against short circuits and overloads

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Efficient conversion from standard bus voltages
Battery-powered equipment requiring high efficiency

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number suffix, such as NOPB for lead-free/RoHS compliance, when ordering. Confirm the specific package variant (e.g., SX vs SD) matches the required footprint. Ensure the supplier source is authorized to guarantee component authenticity and traceability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model for designs requiring a compact surface-mount solution with integrated switching capabilities. The 260kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the thermal performance of the VSON-14 package meets the application's heat dissipation requirements under full load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2673 series of SIMPLE SWITCHER regulators. It shares core architecture with other variants like the LM2673SDX-ADJ but differs in physical packaging. The series is designed for high-efficiency buck conversion applications where board space is limited.
