LM2675N-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675N-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator designed for through-hole mounting in an 8-pin MDIP package. It operates with an input voltage range of 8 V to 40 V and provides a fixed 5.0 V output at up to 1 A load current. The device integrates a 1-A switch with a typical switching frequency of 260 kHz, enabling the use of small external components. It features thermal shutdown and current limit protection, operating reliably across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 1-A power switch for simplified design
• Fixed 5.0 V output option eliminates external feedback resistors
• Includes thermal shutdown and cycle-by-cycle current limiting

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 with 24 V or 48 V bus architectures

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance. Confirm the N suffix corresponds to the MDIP through-hole package variant rather than surface-mount options. Ensure the -5.0 designation matches the required fixed 5.0 V output level for the specific application circuit.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a higher voltage rail up to 40 V. The through-hole MDIP package suits prototyping or applications where manual assembly is preferred. Consider the 260 kHz switching frequency for balancing component size against electromagnetic interference requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 series of SIMPLE SWITCHER regulators. It shares functional similarities with the LM2674 but offers higher output current capability. The series includes adjustable and fixed voltage variants in both surface-mount and through-hole packages to support diverse power management needs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2675N-5.0/NOPB is the direct equivalent of LM2675N-5.0. Cross-reference with LM2675N-3.3/NOPB if a different fixed voltage is needed. Verify pinout compatibility before substituting with other buck converters.
