Power Factor Controller Transformers  
These parts are designed for use with Motorola MC33261  
and MC34261 power factor controllers. They are specifi-  
cally intended for use in AC-DC pre-converter circuits for  
electronic ballast and off-line switching power converter  
applications.  
N2880-AL and N2881-AL utilize standard materials for  
lowest cost. Coilcraft can also supply custom transform-  
ers optimized for specific combinations of output power  
and input voltage.
