LM2670SDX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2670SDX-ADJ/NOPB is a SIMPLE SWITCHER high-efficiency 3A step-down voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 8V to 40V and provides an adjustable output voltage from 1.2V to 37V. The device features a fixed switching frequency of 260kHz and supports a maximum output current of 3A. It utilizes a VSON-14 surface-mount package and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated synchronous rectification for improved efficiency

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the manufacturer's datasheet. Confirm the 'SDX' designation indicates reel packaging when sourcing. Ensure the supplier documentation matches the exact part number to avoid confusion with non-adjustable variants or different package types within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3A continuous current capability is required with an input voltage up to 40V. The adjustable output feature offers flexibility for various load requirements compared to fixed-voltage versions. Consider the VSON-14 package constraints for thermal management and PCB layout space during the design phase.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM267x SIMPLE SWITCHER family, which includes regulators like the LM2673 and LM2679. While sharing similar control architectures and switching frequencies, the LM2670 is distinguished by its 3A current rating and synchronous rectifier design, differing from higher-current or non-synchronous counterparts in the series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2670SD-ADJ/NOPB serves as a direct pin-compatible alternative without the reel packaging specification.
