LM2670SD-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2670SD-12/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 a fixed 12V output at up to 3A. The device integrates a 260kHz switching frequency, synchronous rectification for improved efficiency, and thermal shutdown protection. Packaged in a compact 14-pin VSON (DSO-14) surface-mount format, it supports operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates synchronous rectification to maximize conversion efficiency across the load range.
• Features internal compensation and current limit circuitry to simplify external component selection.
• Includes thermal shutdown protection to safeguard the device during overload or excessive temperature conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems requiring stable 12V supply
• Industrial control power distribution networks
• Telecommunications equipment power stages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'SD-12' confirms the fixed 12V output variant, distinct from adjustable or other voltage versions. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the VSON-14 package footprint matches the PCB layout requirements. Check for lead-free soldering specifications if required by assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an 8V to 40V input source. It is suitable for applications needing up to 3A continuous current with high efficiency. Consider the VSON-14 package size constraints and thermal dissipation needs. Compare against the LM2670ADJ if variable output voltage is needed instead.
