Power Universal Off-Line  
Supplies  
http://onsemi.com  
The NCP1336 hosts a high−performance circuitry aimed to  
powering quasi−resonant converters. Capitalizing on a novel  
valley−lockout system, the controller shifts gears and reduces the  
switching frequency as the power loading becomes lighter. This  
results in a stable operation despite switching events always occurring

in the drain−source valley. This system works down to the 4 valley  
and toggles to a variable frequency mode beyond, ensuring an  
excellent standby power performance.

NCP1336x  
The controller takes benefit of a high−voltage start−up current  
source to provide a quick and lossless power−on sequence. To improve  
the safety in overload situations, the controller includes an Over Power  
Protection circuit which clamps the delivered power at high−line.  
Safety−wise, an adjustable timer relies on the feedback voltage to  
detect a fault. On version B, this fault triggers a triple−hiccup on the  
VCC pin which naturally reduces the average input power drawn by  
the converter. On version A, when a fault is detected, the controller is  
latched−off.

Particularly well suited for adapter applications, the controller  
features two latch inputs: one dedicated to Over Temperature  
protection (OTP) which offers an easy means to connect a pull−down  
temperature sensor like an NTC, and a second one more classical that  
can be used to perform an accurate Over Voltage Protection.  
Finally, a brownout pin which stops the circuit operation in presence  
of a low mains condition is included.
