Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ADDAR' corresponds to the tape-and-reel packaging variant rather than the tube-packaged 'ADDA'. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact thermal pad configuration and pinout defined in the official datasheet to prevent footprint mismatches.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 28 V is required alongside a fixed 3 A output capability. The adjustable frequency feature is critical if electromagnetic interference constraints differ from standard fixed-frequency alternatives. Consider the SO-PowerPAD package for its thermal performance relative to smaller footprints available in other series members.
