NCP1381, NCP1382  
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--Skipt 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  
externally latch the circuit in case of Overvoltage Protection or Over  
Temperature Protection.
