NCP1201  
PWM Current−Mode  
Controller for Universal  
Off−Line Supplies Featuring  
Low Standby Power with  
Fault Protection Modes  
http://onsemi.com  
Housed in SOIC−8 or PDIP−8 package, the NCP1201 enhances the  
previous NCP1200 series by offering a reduced optocoupler current  
with additional Brownout Detection Protection (BOK). Similarly, the  
circuit allows the implementation of complete off−line AC−DC  
adapters, battery chargers or Switchmode Power Supplies (SMPS)  
where standby power is a key parameter.  
The NCP1201 features efficient protection circuitry. When in the  
presence of a fault (e.g. failed optocoupler, overcurrent condition, etc.)  
the control permanently disables the output pulses to avoid subsequent  
damage to the system. The IC only restarts when the user cycles the  
mains power supply.  
With the low power internal structure, operating at a fixed 60 or  
100 kHz, the controller supplies itself from the high−voltage rail,  
avoiding the need of an auxiliary winding. This feature naturally eases  
the designer’s task in battery charger applications. Finally,  
current−mode control provides an excellent audio−susceptibility and  
inherent pulse−by−pulse control.

SKIP  
value, e.g. the output power demand diminishes, the IC automatically  
enters the skip cycle mode and can provide excellent efficiency under  
light load conditions. The skip mode is designed to operate at  
relatively lower peak current so that acoustic noise that commonly  
takes place will not happen with NCP1201.
