Magnetics for IR Dimming Ballast IC
These transformers have been specially engineered for International Rectifier’s IRPLDIM2 Digitally Addressable DALI Dimming Ballast reference design. The Z9265-B (L3) is optimized for International Rectifier’s IR21592 HVIC ballast controller IC while the Z9264-B (L2) is designed for use with the STMicroelectronics PFC L6561D. Free evaluation samples are available by contacting Coilcraft.
