Procurement Notes
Verify component status carefully, as the LC5547LF is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or surplus channels if sourcing is required. Ensure compatibility with existing designs due to potential end-of-life constraints. Check RoHS compliance documentation for regulatory adherence in specific markets.
Selection Notes
Select this component for designs requiring integrated PFC and LED driving in a single stage. The TO-220F-7 package suits applications needing robust thermal performance and through-hole mounting. Consider the internal switch feature to reduce external component count. Evaluate the operating temperature range against environmental conditions.
Part Context
The LC5547LF belongs to the LC554xLF series from Sanken Electric USA Inc., which focuses on single-stage power factor corrected off-line switching regulators. This series targets efficient LED driver solutions with integrated control and switching capabilities. The part number suffix LF indicates lead-free composition compliant with RoHS standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided data. As the LC5547LF is obsolete, alternative components must be selected based on functional equivalence, including PFC integration, dimming support, and package compatibility. Consult manufacturer cross-reference guides for current generation replacements.
