NCP1203  
PWM Current−Mode  
Controller for Universal  
Off−Line Supplies Featuring  
Standby and Short Circuit  
Protection  
http://onsemi.com  
Housed in SOIC−8 or PDIP−8 package, the NCP1203 represents a  
major leap toward ultra−compact Switchmode Power Supplies and  
represents an excellent candidate to replace the UC384X devices. Due  
to its proprietary SMARTMOSt Very High Voltage Technology, the  
circuit allows the implementation of complete off−line AC−DC  
adapters, battery charger and a high−power SMPS with few external  
components.  
With an internal structure operating at a fixed 40 kHz, 60 kHz or  
100 kHz switching frequency, the controller features a high−voltage  
startup FET which ensures a clean and loss−less startup sequence. Its  
current−mode control naturally provides good audio−susceptibility  
and inherent pulse−by−pulse control.  
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 improved efficiency at light loads  
while offering excellent performance in standby conditions. Because  
this occurs at a user adjustable low peak current, no acoustic noise  
takes place.  
The NCP1203 also includes an efficient protective circuitry which,  
in presence of an output over load condition, disables the output  
pulses while the device enters a safe burst mode, trying to restart.  
Once the default has gone, the device auto−recovers. Finally, a  
temperature shutdown with hysteresis helps building safe and robust  
power supplies.
