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.
