Document 245 Flyback Transformers
These transformers have been specially developed for
use in flyback power supplies with the ON Semiconductor NCP1200 PWM Current-Mode Controller. They are
designed for universal input, 85 – 265 Vac. For ON Semiconductor
NCP1200 Controller Coilcraft can also custom engineer a transformer to meet
your specific requirements. For free evaluation samples,
