Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix against official Texas Instruments documentation to confirm the reel packaging format and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel specifications for automated assembly processes. Cross-reference the manufacturer's latest datasheet to validate any potential revisions or obsolescence notices before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 500 mA buck converter with adjustable output is required. It is suitable for designs needing a wide input voltage range up to 42 V. Consider the SO-PowerPAD-8 package for thermal performance and space constraints. Verify that the external component selection aligns with the desired switching frequency and output voltage settings specified in the application circuit guidelines.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM22671 series of SIMPLE SWITCHER regulators from Texas Instruments. The series is designed for general-purpose DC-DC conversion applications. The 'MRX' designation indicates the specific reel packaging variant, while 'ADJ' confirms the adjustable output capability. The '/NOPB' suffix denotes lead-free and halogen-free construction compliant with environmental standards.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM22671MR-ADJ/NOPB is a tube-packaged equivalent with identical electrical characteristics. LM22671MRX-5.0/NOPB offers a fixed 5.0 V output instead of adjustable. LM22674MRX-ADJ/NOPB provides similar functionality but may differ in specific thermal or pinout details requiring verification.
