Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2670SD-12/NOPB

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 manufactured by Texas Instruments, formerly National Semiconductor. It operates with a fixed 12V output and supports an input voltage range of 8V to 40V. The device integrates a synchronous rectifier for improved efficiency and features a switching frequency of 260kHz. It is housed in a 14-VSON package and functions within a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a synchronous rectifier to enhance conversion efficiency compared to traditional diode-based designs.
Utilizes the SIMPLE SWITCHER architecture to minimize external component count for compact board layouts.
Features internal frequency compensation and current limit protection for stable operation.

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment requiring efficient step-down conversion
Industrial control systems operating from 24V or 48V buses

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation, as National Semiconductor was acquired by Texas Instruments. Confirm the suffix /NOPB indicates lead-free and RoHS compliance. Ensure the package type matches the design requirements, specifically the 14-VSON footprint. Cross-reference the specific revision against the official datasheet to confirm pinout and electrical characteristics remain unchanged.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an input voltage between 8V and 40V. The integrated synchronous rectifier makes it suitable for applications prioritizing efficiency over cost. Consider the 260kHz switching frequency for balancing component size and electromagnetic interference. Verify thermal performance under maximum load conditions given the VSON package constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2670 series of SIMPLE SWITCHER regulators. It is distinct from the adjustable version (ADJ) and other current variants like the LM2676 or LM2677 which may differ in current handling or feature sets. The SD suffix denotes the specific VSON package variant used in this configuration.
