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.

MARKING  
DIAGRAMS  
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.  
Current−mode control also provides an excellent input audio  
susceptibility and inherent pulse−by−pulse control. Internal ramp  
compensation easily prevents sub−harmonic oscillations from taking  
place in continuous conduction mode designs.

When the current setpoint falls below a given value, e.g. the output  
power demand diminishes, the IC automatically enters the so−called  
skip cycle mode and provides excellent efficiency at light loads.  
Because this occurs at a user adjustable low peak current, no acoustic  
noise takes place.

The NCP1216 features an efficient protective circuitry, which in  
presence of an over current condition disables the output pulses while  
the device enters a safe burst mode, trying to restart. Once the default  
has gone, the device auto−recovers.
