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.
