These transformers have been specially developed for use
in flyback and forward power supplies with the ON Semi-
conductor NCP1200 PWM Current-Mode Controller. They
are designed for universal input, 85 – 265 Vac.
Coilcraft can also custom engineer a transformer to
meet your specific requirements. For free evaluation
samples, contact Coilcraft or visit www.coilcraft.com.
