Procurement Notes
This component is officially listed as obsolete by the manufacturer. No new production units are available through standard distribution channels. Engineers must verify end-of-life status before design finalization. Sourcing should focus on existing surplus stocks or authorized distributors holding remaining inventory, though availability is not guaranteed. Design-in activities are discouraged due to discontinuation.
Selection Notes
Select this part only if legacy compatibility is required for existing designs utilizing the EL7513 series. New designs should consider alternative active components from the manufacturer's current portfolio. Verify that the TSOT23-8 package dimensions and pinout match the target PCB layout constraints. Ensure the input voltage range and LED forward voltage requirements align with the step-up topology capabilities.
Part Context
The EL7513 belongs to the Intersil/Renesas line of power management ICs focused on LED driving solutions. It represents a specialized step-up regulator architecture optimized for portable applications requiring efficient white LED illumination. The product history reflects the transition from Intersil to Renesas Electronics Corporation.
Replacement Considerations
No specific public substitute part numbers are documented in the provided source material. Consult the manufacturer's official obsolescence notices or current product selection guides for modern equivalents.
