Procurement Notes

Verify availability status carefully as the part may be subject to limited supply or factory special orders. Confirm RoHS compliance details through official documentation before integration. Ensure compatibility with existing dimming infrastructure, particularly if utilizing the 0-10V interface via the iW339 companion component. Validate thermal management requirements for the specified operating temperature range.

Selection Notes

Select this component for designs requiring integrated PFC and high efficiency in commercial SSL applications. Consider the SOIC-8 package constraints and the need for external components when implementing specific dimming protocols. Evaluate the 90W power ceiling against load requirements. Ensure the 72-90kHz switching frequency aligns with EMI constraints of the target system.
