NCP1216/D

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

the device enters a safe burst mode, trying to restart. Once the default

has gone, the device auto−recovers.
