| Document 145 Power Factor Controller Transformers These parts are designed for use with Motorola MC33261 and MC34261 power factor controllers. They are specifically 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 transformers optimized for specific combinations of output power and input voltage.
