LM2670T-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2670T-5.0/NOPB is a SIMPLE SWITCHER power regulator from Texas Instruments, configured as a fixed-output buck converter with a 5 V output. It supports an input voltage range of 8 V to 40 V and delivers up to 3 A of continuous output current. Operating at a switching frequency of 260 kHz, the device utilizes a TO-220-7 through-hole package. It functions within a temperature range of -40 °C to +125 °C and incorporates internal current limiting for protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic switching regulator designed for high-efficiency step-down conversion
• Built-in current limit circuitry provides inherent overcurrent protection
• Fixed 5 V output configuration eliminates external feedback resistor requirements

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in industrial control systems
• Power supply stages for embedded computing hardware
• Distribution networks requiring 5 V rails from higher bus voltages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' indicates lead-free construction and RoHS compliance. Confirm the 'T' designation corresponds to the TO-220-7 through-hole package variant rather than surface-mount options. Ensure the '-5.0' suffix matches the required fixed 5 V output specification for your design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a robust through-hole solution is required for 3 A loads. The 260 kHz frequency allows for smaller passive components compared to lower-frequency regulators. Verify that the thermal performance of the TO-220 package meets the heat dissipation needs of the specific application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM267x family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2673 and LM2677 but is distinguished by its 3 A current rating and specific TO-220 packaging. The family is characterized by integrated power switches and simplified external component requirements.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2670T-5.0/NOPB serves as a direct functional equivalent to the older LM2670T-5.0. Cross-reference with LM2673T-5.0/NOPB if a 3 A current rating is acceptable but different thermal characteristics are needed.
