NCP1200  
PWM Current−Mode  
Controller for Low−Power  
Universal Off−Line Supplies  
Housed in SOIC−8 or PDIP−8 package, the NCP1200 represents a  
major leap toward ultra−compact Switchmode Power Supplies. Due to  
a novel concept, the circuit allows the implementation of a complete  
offline battery charger or a standby SMPS with few external  
components. Furthermore, an integrated output short−circuit  
protection lets the designer build an extremely low−cost AC−DC wall  
adapter associated with a simplified feedback scheme.  
With an internal structure operating at a fixed 40 kHz, 60 kHz or  
100 kHz, the controller drives low gate−charge switching devices like  
an IGBT or a MOSFET thus requiring a very small operating power.  
Due to current−mode control, the NCP1200 drastically simplifies the  
design of reliable and cheap offline converters with extremely low  
acoustic generation 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 skip cycle  
mode and provides excellent efficiency at light loads. Because this  
occurs at low peak current, no acoustic noise takes place.

Finally, the IC is self−supplied from the DC rail, eliminating the  
need of an auxiliary winding. This feature ensures operation in  
presence of low output voltage or shorts.
