Power Factor Controller Transformers Document 145 Document 145 Revised 01/06/09 These parts are designed for use with Motorola MC33261 and MC34261 power factor controllers. They are spe- cifically intended for use in AC-DC pre-converter cir- cuits 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 trans- formers optimized for specific combinations of output power and input voltage.
