LM2671N-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2671N-12/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-efficiency power conversion. It integrates a 0.5A switch and operates at a fixed switching frequency of 260 kHz. The device provides a fixed output voltage of 12V with a maximum output current of 500mA. It accepts an input voltage range from 7.5V to 40V. The component is housed in an 8-pin PDIP package and supports through-hole mounting. It functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 0.5A power switch for compact design
• Fixed 260 kHz switching frequency reduces external component size
• Includes thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment power supplies
• General-purpose DC-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-8 through-hole package variant. Confirm 'NOPB' indicates lead-free and RoHS compliance status. Ensure the '12' designation matches the required 12V fixed output voltage. Cross-reference the manufacturer part number with official datasheets to validate pinout and electrical specifications before integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a through-hole solution is required for low-current applications. It is suitable for designs needing a fixed 12V output from a higher voltage rail. Consider the 260 kHz frequency for balancing efficiency and passive component size. Verify that the 500mA load requirement does not exceed the integrated switch rating under all operating conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2671 family of SIMPLE SWITCHER regulators. It shares core architecture with adjustable and other fixed-voltage variants like the LM2671N-ADJ or LM2671M series. The primary distinction lies in the fixed output voltage and the PDIP package type compared to SOIC alternatives.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2671N-12/NOPB is the direct equivalent. LM2671N-ADJ/NOPB offers adjustable output but requires external resistors. LM2671MX-12/NOPB provides the same electrical performance in an SMD SOIC-8 package.
