NCP1216, NCP1216A

PWM Current-Mode

Controller for High-Power

Universal Off-Line Supplies

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.

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.

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.

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.
