Magnetics for IR Dimming Ballast IC
These transformers have been specially engineered
for International Rectifier’s IRPLDIM2 Digitally Addres-
sable 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.
