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.
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
