NCP1216, NCP1216A
PWM Current-Mode
Controller for High-Power
Universal Off-Line Supplies
Housed in a SOIC−8 or PDIP−7 package, the NCP1216 represents an enhanced version of NCP1200 based controllers.
Due to its high drive capability, NCP1216 drives large gate−charge
MOSFETs, which together with internal ramp compensation and built−in frequency jittering, ease the design of modern AC−DC adapters.
With an internal structure operating at different fixed frequencies, the controller supplies itself from the high−
voltage rail, avoiding the need of an auxiliary winding.
This feature naturally eases the designer task in some particular applications, e.
g.
battery chargers or TV sets.
