Procurement Notes
Verify the exact part number suffix against the manufacturer's current datasheet to ensure correct pinout and thermal specifications. Confirm RoHS compliance status and lead-free designation as per the specific manufacturing batch documentation provided by Infineon or authorized distributors before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring a single-stage buck conversion from high-voltage DC sources directly to LED loads. Ensure the application voltage does not exceed the 200V rating and that the SOIC package thermal dissipation capabilities meet the system's power requirements without additional heatsinking.
Part Context
This component belongs to Infineon's portfolio of power management integrated circuits designed for robust operation in demanding environments. It represents a specialized solution for high-voltage LED driving, distinguishing itself from standard low-voltage regulators by its ability to handle significant potential differences between input and output stages.
Replacement Considerations
Consult official Infineon substitution guides for equivalent high-voltage buck LED drivers. Verify compatibility regarding pin configuration, thermal performance, and control interface before replacing with alternative part numbers.
