SMT Power Magnetics ForONSemiconductor
NCP1216A Controller
Coilcraft’s C0972-AL transformer and B0754-AL inductor
were developed specifically for the ON Semiconductor
NCP1216A PWM Current-Mode Controller.
They are specified in application note AND8161/D along
with Coilcraft’s DS3316P-103 and DS3316P-102 shielded
inductors. Refer to the separate data sheet for additional
information about the DS3316 Series of inductors
The C0972-AL features very low DCR, excellent leak-
age inductance and 1500 V Isolation from the primary
and auxiliary windings to the secondary.
The B0754-AL is the output inductor and features four
separate windings connected in parallel to minimize
power losses and to limit temperature rise.
