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.
