Procurement Notes
Verify the specific suffix 'ADR' against the manufacturer's official datasheet to confirm pinout and package dimensions. Ensure the component meets RoHS compliance requirements as indicated by the 'NOPB' designation. Cross-reference the ordering information with the latest Texas Instruments documentation to avoid discrepancies in revision levels or packaging specifications.
Selection Notes
Select this component for applications requiring integrated PFC and primary side regulation without optocouplers. Consider the 8-SOIC package constraints and the 2 A output current limit when designing the power stage. Evaluate the thermal performance within the specified -40°C to +125°C operating range to ensure reliability under varying environmental conditions.
