MARKING  
Housed in SO–8 or DIP8 package, the NCP1200 represents a major  
leap toward ultra–compact Switch–Mode Power Supplies. Thanks 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.  
Thanks to current–mode control, the NCP1200 drastically simplifies  
the design of reliable and cheap offline converters with excellent  
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 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.
