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.
