Supply original NCP1216P100G, PMIC - AC DC Converters, Offline Switchers, by ON Semiconductor

PWM Current-Mode Controller for High-Power Universal Off-Line SuppliesHoused 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.
