Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ADDA' corresponds to the tube packaging variant when ordering. Confirm the manufacturer source is Texas Instruments to ensure authenticity. Check for RoHS compliance status as indicated in official documentation. Ensure the order quantity matches the factory tube pack size requirements. Validate the part number against the latest datasheet revision to avoid obsolete stock.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 400 kHz frequency is required to minimize passive component footprint. It is suitable for designs needing a wide input voltage range up to 36 V. The 3 A current capability supports moderate load applications. Consider the thermal performance of the PowerPAD package for heat dissipation needs. Verify that the adjustable output range meets the target voltage requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR33630 series of synchronous buck converters. It shares core electrical specifications with variants like LMR33630ADDAR but differs in packaging. The 'ADDA' designation specifically indicates the tube package format. Other series members may offer different switching frequencies or pinouts.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR33630ADDAR is a direct functional substitute with identical electrical characteristics but utilizes tape-and-reel packaging instead of tubes. Designers must verify board space compatibility if transitioning between tube and reel formats.
