Low-- Standby High
Performance PWM
Controller
Housed in a SO--14 package, the NCP1381/82 includes everything
needed to build rugged and efficient Quasi--Resonant (QR) Switching
Power Supplies. When powered by a front--end Power Factor
Correction circuitry, the NCP1381/82 automatically disconnects the
PFC controller in low output loading conditions (with an adjustable
level), thus improving the standby power. This is particularly well
suited for medium to high power offline applications, e.g. notebook
adapters. 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 an adjustable low peak current together

with a proprietary Soft--Skip t technique, no acoustic noise takes
place. Skip cycle also offers the ability to easily select the maximum
switching frequency at which foldback and standby take place.
The NCP1381/82 also features several efficient protection options
like a) a short--circuit / overload detection independent of the auxiliary
voltage b) an auto--recovery brown--out detection and c) an input to
