LM22670QMRE-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM22670QMRE-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER step-down voltage regulator featuring a fixed 5 V output and 3 A maximum current capability. It operates from an input voltage range of 4.5 V to 42 V with a standard switching frequency of 500 kHz. The device utilizes an SO-PowerPAD-8 package for surface mount installation and supports an operating temperature range from -40 °C to +125 °C. It holds AEC-Q100 qualification for automotive applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-side and low-side power switches enable efficient buck conversion without external components.
• Frequency synchronization pin allows multiple regulators to operate in phase or out of phase to reduce input ripple.
• Built-in thermal shutdown and current limit protection ensure robust operation under fault conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Automotive infotainment systems requiring regulated power rails
• Industrial control boards utilizing wide input voltage ranges
• Distributed power architectures in telecommunications equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the QMRE suffix corresponds to the specific SO-PowerPAD-8 tape and reel packaging configuration. Ensure the part number matches the fixed 5.0 V output variant rather than adjustable versions within the same family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V rail is required at up to 3 A from inputs up to 42 V. The integrated switch design reduces external bill of materials compared to discrete solutions. Consider the thermal performance of the PowerPAD package for heat dissipation requirements in enclosed environments.
