LM2672N-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2672N-12/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-efficiency power conversion. It operates with an input voltage range of 8V to 40V and provides a fixed 12V output at up to 1A load current. The device integrates a 1A switch and operates at a switching frequency of 260kHz. It features thermal shutdown and current limit protection. The component is housed in an 8-pin PDIP package and supports operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 1A power switch for low external component count
• Includes internal thermal shutdown and current limiting protection
• Offers fixed output voltage options for simplified design

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring efficient step-down conversion
• General-purpose DC/DC power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP package variant rather than the SOIC or TO-263 packages found in other LM2672 derivatives. Confirm RoHS compliance status via the manufacturer datasheet as suffixes may indicate environmental variations. Ensure the fixed 12V output matches the system requirement, as adjustable versions exist within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12V output is required from an 8V to 40V input source with up to 1A capacity. The PDIP package is suitable for through-hole mounting applications where surface-mount options are not feasible. Compare against the LM2672MX-ADJ if variable output voltage is needed instead of a fixed setting.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2672 family of SIMPLE SWITCHER regulators, which are known for reducing external component requirements. The family includes variants with different output voltages and packages, such as the SOIC (M) and TO-263 (S) packages. The LM2672N specifically denotes the through-hole PDIP configuration within this line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2672N-12/NOPB is the direct lead-free replacement for the non-NOPB version. For pin-compatible alternatives, consider the LM2576 series, though switching frequencies and efficiency characteristics will differ.
