Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2670SD-ADJ

LM2670SD-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2670SD-ADJ/NOPB is a SIMPLE SWITCHER high-efficiency 3A step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 8V to 40V and provides an adjustable output voltage between 1.2V and 37V. The device features a fixed switching frequency of 260kHz and includes internal compensation for minimal external component requirements. It utilizes a 14-pin VSON package and supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous rectification for improved efficiency
Internal frequency compensation reduces external component count
Fixed 260kHz switching frequency enables compact passive design

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment power management
Industrial control system power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number suffix, specifically /NOPB, to confirm lead-free compliance and specific packaging configuration. Confirm the 'SD' suffix corresponds to the 14-VSON package variant rather than other package options within the LM2670 family. Cross-reference the manufacturer datasheet revision to ensure compatibility with current design specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 3A continuous output current is required from an 8V to 40V input source. The adjustable output version allows flexibility in setting the target voltage via external resistors. Ensure the application requires synchronous rectification for higher efficiency compared to non-synchronous buck converters in similar current ranges.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM267x SIMPLE SWITCHER family of monolithic DC-DC converters. It shares architectural similarities with the LM2673 and LM2679 but is distinguished by its 3A current rating and integrated synchronous rectifier. The family is designed for high-efficiency step-down conversion with minimal external circuitry.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2670SDX-ADJ/NOPB is the reel-packaged equivalent of the tube variant. LM2670SD-ADJ without the NOPB suffix indicates older manufacturing versions which may differ in RoHS compliance.
