For ON Semiconductor
NCP1200 Controller
Flyback Transformers
These transformers have been specially developed for
use in flyback power supplies with the ON Semiconduc-
tor 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.

1. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc
2. Leakage inductance tested at 100 kHz, 0.1 Vrms
3. Isolation tested between primary and secondary on all parts and be-
tween primary and auxiliary on Z9260-AL.
4. Primary to secondary turns ratio specified with secondary windings con-
nected in parallel.
5. Operating temperature range -40°C to +85°C.
6. Electrical specifications at 25°C.
