NCP1239  
Low−Standby High  
Performance PWM Controller  
Housed in SO−16 the NCP1239 represents a major leap toward  
ultra−compact Switch Mode Power Supplies specifically tailored for  
medium to high power off−line applications, e.g. notebook adapters.  
The NCP1239 offers everything needed to build a rugged and efficient  
power supply, including a dedicated event management to drive a  
Power Factor Correction (PFC) front−end circuitry. The circuit  
disables the front−end PFC stage while still in fault or standby  
conditions by interrupting the PFC controller powering for improved  
no−load consumption figures. As soon as normal operating mode  
recovers, the NCP1239 feeds back the PFC that wakes−up.

When power demand is low, 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.
