1 / 18 page © Semiconductor Components Industries, LLC, 2016 May, 2016 − Rev. 16 1 Publication Order Number: 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.
